Title: Story of one CB-1
Post by: Velos on September 27, 2016, 05:08:52 PM
Hello everybody!
I was recently chatting with a_morti and he said that I should make a post here :)
So here it is: a little story of one CB-1 that is living with bears under sounds of balalaika…

Autumn 2004
Few weeks after purchasing.
I already have my first fall.

Winter 2005 - 2006
After first crash.

(https://pp.userapi.com/c4117/u831541/93026534/x_aa948d4a.jpg)

My first experience of integration non-stock parts.
Front fork, disk and brakes from CB400SF'94.

(https://pp.userapi.com/c4117/u831541/93026534/x_1f6d3288.jpg)

2007
Frame was prepared for new swingarm integration.

(https://pp.userapi.com/c4117/u831541/93026534/x_49b90acd.jpg)

Assembly at home :)

(https://pp.userapi.com/c4117/u831541/93026534/x_facff3e6.jpg)

Rear cowl and tank are still gloss.

(https://pp.userapi.com/c4117/u831541/93026534/x_49df9e14.jpg)

2008
Black matte color.
My friend wished to buy it.
But it still will be stored by me...
At this time I already bought CBR600F4i, so CB-1 goes to stand without riding.

(https://pp.userapi.com/c636723/v636723541/15a1f/DTLXbAO1blc.jpg)


2009
Some photos for our local moto-magazine.

(https://pp.userapi.com/c4117/u831541/93026534/x_ab2b03f1.jpg)
(https://pp.userapi.com/c4117/u831541/93026534/x_38189867.jpg)

2011
My friend takes cb-1 to his garage.

2014
For 6 years of standing there were no even a one ride on the road by my friend.
I decided to buy my CB-1 back :)

2015
I am looking for a spark )
Left engine cover was welded for 6 or 7 times (during my ownership).
For last 4 years the engine has never started. So hall sensor finally have missed it’s normal position because of ambient temperature changes.

(https://pp.userapi.com/c631321/v631321541/5bfa/opOddphsj7k.jpg)

There also was a mess in carburetors due to 4 years of standing…
I had to replace 1 idle jet and all locking needles.

Video :) (https://youtu.be/NeZwpg2NBzE)

2016 – nowadays

Here starts the second “upgrade marathon”.
It is still not finished yet.
When I was buying my CB-1 back I had a goal to make it in a way I always wanted.
The goal is not reached yet, but it becomes closer and closer.
There is no any common sense in this project. There is no goal of money saving (I don’t want to make even a preliminary estimate of the total cost).
I like this bike. He is dear to me as a memory of my father from one hand.
From the other hand I am moved by a desire: “I wish!”   

Fork
I have inadvertently found this one:

(https://pp.userapi.com/c631321/v631321541/5c03/Ug9auzKiLcs.jpg)
(https://pp.userapi.com/c631321/v631321541/5c0c/JVRrJiQevUQ.jpg)
(https://pp.userapi.com/c631321/v631321541/5c15/51whgOqCf5k.jpg)

This is a stock front end from Ducati 749 with brake calipers )
It is very nice, except the huge diameter of steering axle.
Steering axle is so big that there is no room if you will insert it in CB-1’s frame.
After a long period of thinking there was a decision:

(https://pp.userapi.com/c631321/v631321541/5c2f/YVxnhXTlfXE.jpg)
(https://pp.userapi.com/c631321/v631321541/5c41/kNCbJ6tdT8U.jpg)
(https://pp.userapi.com/c631321/v631321541/5be8/Kk56zneIlmg.jpg)

The drawing on a last picture has some mistakes, which were corrected during machining (in case if someone else will decide to perform this madness).

New steering axle for stock CB-1’s bearings:

(https://pp.userapi.com/c630328/v630328541/495c8/6Czxf1GtAkI.jpg)

Upper 749 bridge is beautiful, but it’s also not applicable for installation. There is a huge hole for steering axle and steering damper mount is butting to the fuel tank.

(https://pp.userapi.com/c631321/v631321541/5c4a/7RkuwiSK_DU.jpg)

This 749 fork has a rare diameter (53 mm), so I had the only option: to make my own upper bridge (with blackjack and hookers :) ).

(https://pp.userapi.com/c631321/v631321541/5ca8/_X7SiKF9wpk.jpg)

And polish it...

(https://pp.userapi.com/c631321/v631321541/5ccc/4eC_FMvuPyg.jpg)

Lower stem also needed to be upgraded.

(https://pp.userapi.com/c631321/v631321541/5cd5/tktb3ffAKm4.jpg)

First of all I needed to press in new steering axle.
The other problem is steering limiter. Stock 749 steering limiters didn’t give enough space for steering.
So I decuded to cut it off... And polish )

(https://pp.userapi.com/c631321/v631321541/5ce7/dlmVDpM-r0w.jpg)

In assembly:

(https://pp.userapi.com/c631321/v631321541/5cf9/IRg1cQ7UhGw.jpg)

For steering limiters I came up with this construction:

(https://pp.userapi.com/c630321/v630321909/2da2f/QmiwDhq3YjU.jpg)

After measuring stock CB-1 limiters new construction was applied to 749 stem with welding:

(https://pp.userapi.com/c636723/v636723541/158fd/bfF6jxKNEj4.jpg)
(https://pp.userapi.com/c636723/v636723541/15906/BU44XA4A0b8.jpg)
(https://pp.userapi.com/c636723/v636723541/158f4/j4fxSVgP7kM.jpg)

And of course polishing. I can’t allow myself not to use it since 2007 :)

(https://pp.userapi.com/c615824/v615824909/f406/HP0yeewXlRI.jpg)
(https://pp.userapi.com/c615824/v615824909/f40f/zlLHd1eF2uk.jpg)

Wheels
I suppose Italian engineers loves fat sizes :)
Diameter of new wheel axle is 25.
So there was no option to keep stock CB-1/CB400SF wheel.
I used wheels from Ducati Monster 800.

(https://pp.userapi.com/c631321/v631321541/5c25/5T-WxCpNpK0.jpg)

After some measurement I realized that it will be impossible to insert Monster rear wheel in NC29 swingarm. In no way…
So I used 5`` wheel from SF400VTEC.
The advantage of using this wheel is that there is no need to remake ant mounts. I had to make only two new spacers.

(https://pp.userapi.com/c631321/v631321541/5c7a/wdWilmbVufk.jpg)

I used a powder painting .

(https://pp.userapi.com/c631321/v631321541/5c96/OrXKlp56iPA.jpg)

For rebuilding period I used temporary tyres. They are nearly close to those that I want to use on the road.

(https://pp.userapi.com/c631321/v631321541/5c9f/_dG0hTzpXPY.jpg)

BTW, I want to use:
- Front 120/60-17 on a 3.5’’ rim (the rim is Brembo!).
- Rear 160/60-17 on a 5.0’’ rim.
In fact it’s the only change from stock geometry.
All other dimensions stayed the same!

Brakes
I was able to get front brake rotors with front wheel (320mm).

(https://pp.userapi.com/c631321/v631321541/5c54/48shDWb8FIo.jpg)

Also I got stock 749 4-pistons brake calipers with front fork.

(https://pp.userapi.com/c631321/v631321541/5c38/j9WDv7tQKTA.jpg)

Despite the fact that wheel and fork a both came from Ducati they still needed an adjustment.
Monster’s front wheel is 10mm (5mm each side) thinner in rotor mount than 759’s wheel.
First I tried to make rotor spacers, but they didn’t match (rotor can’t find his center because of heigh).
Then I tried to develop an adaptor. I even almost finished drawing:

(https://pp.userapi.com/c630328/v630328541/495d0/y6ukl0P3AOE.jpg)

But during drawing I realized that there is no need in such adapter.
The concept is simple:

(https://pp.userapi.com/c630027/v630027909/21ee6/-RnYS3TLKQo.jpg)

Rear brake stayed stock from CB-1.

Front master cylinder was used from stock Hayabusa’07 (my second bike :) ).
I will test it on the road.

Attachments

I was looking for different options during writing this article in original language. To save the original exposition: I was looking for switches, clutch lever mount, etc.
Clip-ons were used form 749:

(https://pp.userapi.com/c633825/v633825909/2518a/emuECNVAELI.jpg)

Initially I was planning to use sotck CB-1 gauge. So upper bridge was made with mounts for it. But I was unable to cope with myself and bought this:

(https://pp.userapi.com/c636723/v636723541/158e2/zyZo2ILLSeg.jpg)
(https://pp.userapi.com/c636723/v636723541/158eb/Vv409kVKEQc.jpg)

At the moment of writing original post I didn't decide how to mount it.

Rear shock
I used a CBR893 shock.
I found info about it’s compability on this forum :) 
In 2007-2008 I installed NC29 swingarm without progression.
Link. (http://hondacb1.proboards.com/thread/44/russian-cb-1)
So I have performed spring swap.
I also took it to hydraulics workshop for service (gas/oil/seal replacement).

(https://pp.userapi.com/c631321/v631321541/5c8c/2u-jznHJD3I.jpg)

At this checkpoint it looked like that:

(https://pp.userapi.com/c637130/v637130541/93a/PIRoo-v5ssM.jpg)
(https://pp.userapi.com/c637130/v637130541/943/UDiPFUv7y5Y.jpg)
(https://pp.userapi.com/c637130/v637130541/94c/DjXIAdTvqFY.jpg)

Fork was “capitally” installed. All attachments were putted for clarity  :)

Some time later

Switches and gauge have found their places.
I always was dreaming about separated throttle grip from switch. Now my dream come true ))

(https://pp.userapi.com/c636122/v636122541/2ac93/bvl9OVpxPx4.jpg)
(https://pp.userapi.com/c636122/v636122541/2ac9c/sJibPglbLcg.jpg)
(https://pp.userapi.com/c636122/v636122541/2aca5/2CtS9CB0EV0.jpg)

Currently I am waiting for brake and clutch levers. I have ordered them from Titax. Those chez guys are not hurrying :)
But rearsets are already here!

(https://pp.userapi.com/c626227/v626227541/2806a/3mzClBMyhx4.jpg)
(https://pp.userapi.com/c636122/v636122541/2ac68/Q7vkWrwlqIQ.jpg)

It is a Sato racing rearser for CBR929/954.
Their quality is perfect and they are compatible with CB-1.
I had to made only two modifications:
-   use stock adapter for shift axle ( I had to pull it out from stock);
-   use additional spacer between frame, because NC29 swingarm is very “fat”.

(https://pp.userapi.com/c604524/v604524541/2a167/fxveY81E3q0.jpg)

The only disadvantage is non-folding pegs.
I have used this “spare part” from China :)

(https://pp.userapi.com/c636122/v636122541/2ac78/SDLjllhcLsQ.jpg)

For headlight I have developed this construction:

(https://pp.userapi.com/c836130/v836130541/721/ZWDqMWOdoxQ.jpg)
(https://pp.userapi.com/c836130/v836130541/73c/4X09vPopMsU.jpg)

It should looks like this:

(https://pp.userapi.com/c604524/v604524541/2a15e/tWlDXV5S8cE.jpg)
(https://pp.userapi.com/c836130/v836130541/733/mqGOvQ7V6nw.jpg)

I am going to use rubber adapters in mounting plates (for compensation of vibrations):

(https://pp.userapi.com/c636122/v636122541/2ac81/wXUw5zGMz-g.jpg)


At the moment it looks like this:

PS: sorry for my English :)
PPS: during making of this translation I get a photo from a CNC-master:

(https://pp.userapi.com/c836239/v836239541/2ca9/20GtKBWFPbs.jpg)

Next steps:
-   rear cowl/rear subframe/seat modifitcation;
-   piston rings / valve seal replacement (stock);
-   muffler welding;
-   cbr400RR camshaft sawp;
I have read a lot about FCR carbs, but I am not sure I will be able to tune them here (no specialists, no spare parts, no adavantage for road use)…

Like, just wow! So much time, money and passion.

Great work, when do you think it will be finished?

Thanks for sharing.

Thanks :)
I think I will finish it in spring 2017.
To be honest I have very little time to stay in garage...

PS: I have missed a "Brake" section.
It is on it's place now :)

No....I think he wants to exchange his wife for the "whole" CB1...not just some parts.

Time to make some keepalive/update.

Engine works have been started.

(https://pp.userapi.com/c637320/v637320541/1779f/VLLs1LE27hE.jpg)

Inspection after disassembly have showed that it is necessary to replace second gear and rod's bearings.
In addition to this I have also ordered new piston rings, crankshaft's bearings, rod's bolts and nuts and new counter-shaft with root bearings.
It's a pity, but for now it's impossible to order new gears... I had to buy used...
Keep your transmission in safe!

While engine is assembling I have finished my ex upgrade (9 years have past): NC29 progressive linkage.
Bye bye mister "central stand linkage".
Hello mister "progressive shock linkage". Wellcome to the world of aftermarket shocks :)

It's only some of them... Much more to come...
I think at this point I should make a new tag.

2017
The third part of upgrade marathon begins here.
To be continued...

My wife would have a fit if I spent so much on parts ;-)

Nice polishing, must have taken ages. Will you clear coat them?

One more person is talking about his wife (and again I am not sure that I understand you correctly).
I hope that everything is fine in your families :)
I don't want to make any influence on other's relationships )))

As for clear coat - I am not going to do anything more with those parts.
They are ready for installation.

sorry...but I must make this comment.
I'm sick to death when "guys" say "my wife would kill me if.....".
FAK! grow a set testicles guys....sheesh. I mean, I coordinate my purchases with our home finances but crap mates......don't get so hung up on your wives emotions about what you do or don't do with YOUR hobby.

I buy my $h!t for my CB1. I buy my $h!t for my 919...........PERIOD.
I dont' ASK for permission to buy stuff.....sheesh. Man I'm sick of reading those lines..."my wife would be pissed off if...."

Guys, the comment about my wife was intended as a joke and should have been taken as such. Maybe there are some cultural differences in our communications? I too will buy what I like for my bike. And VintageHunter my balls are quite big enough thank you ;-)

I asked about the clear coat because I was concerned that the polished parts would tarnish quickly. Here in the UK with our salty roads, especially at this time of year I would have thought that they would be in a poor state quickly. Or am I wrong?

Clear coat = varnish, right?

It's useless to use it with polished parts bacause it won't persist on a smooth part.

I made my first polishing in 2007. There is no any oxidation.
It can became a little dim over some time. But you can make it shine again with a felted circle and polish paste.

It is mostly manual work.
You will need sandpaper with different grit sizes, that can be attached to a drill or angular grinding machine. Also you will need felted circle and polishing paste (can't say which one is available in your country).
1) Get rid off factory paint. It's the most difficult step. Big areas can be machines with a drill/grinding machine. Little areas, corners and pits should be completed by hands. You can also use scotch-brite.
2) You should handle your detail with different grit sizes, starting with coarse and finishing with fine sizes.
3) make a final handling of your detail with felted circle and polishing paste.

Story continues...

Rear suspension - part 2
As people say: if you don't succeed, try again!
During performing shock spring swap from CB-1 to CBR893 (900) I encountered with a problem: stock CB-1's spring is longer than 893's. That meant a pre-load problem (left - stock CB-1 spring, right - 893):

(https://pp.userapi.com/c639331/v639331541/bda0/n_SevH9ddoI.jpg)
 
Then I decided to keep 893 shock "as is" and integrate it with a stock NC29 progressive linkage (I wrote about it here (http://www.hondacb1.org/forum/index.php/topic,5290.msg25373.html#msg25373)).
I was naive and self-confident, because I was sure that I will be able to do it without knowing stock NC29 linkage position with full rebounded shock. As a result - I made this linkage wrong :)
In addition I made some consultations with racers and some measurements which brought me to a conclusion: 893's shock will not work properly on CB-1's weight.
The best option will be to use CBR600F4i shock with some valve tuning.
I bought 600F4i shock and made a visit to NC29 owner to measure his linkage position.
When I was "locked and loaded" with all necessary info, it was time for second attempt.


I got this F4i shock in terrible condition:

(https://pp.userapi.com/c639331/v639331541/bcda/k4JL3LSYx4w.jpg)

Shock was disassembled:

(https://pp.userapi.com/c639331/v639331541/9862/I9GL8gVyqoE.jpg)

This shock is compatible with NC23 and NC29. To integrate it into CB-1 with NC29 swingarm it should be extended/elongated:

(https://pp.userapi.com/c639331/v639331541/9898/q81Q8XqX3D8.jpg)

And it should be painted :)

(https://pp.userapi.com/c639331/v639331541/bd6a/m6Q_BKMma2w.jpg)

During painting works racetech kit had arrived. It is calculated for bike and pilot weight.
It had arrived fast but one part was missing. I am still awaiting for it :(

Velos,

Thank you for keeping your thread updated with your progress.  Your passion for the old bike we ride is very inspiring.

I am interested in what compression and rebound shimstacks you will be running on the rear shock.  Will the RT shock piston allow you to run both a high and low speed stack on both sides?  If so, would you mind posting what you went with on each stack?

Also, I am interested in your experience with the aftermarket ignition timing setup.  It looks like you will have some interesting adjustability for a modified powertrain.  Are you changing lobs on the engine cam?

Looking forward to your thread.  Also, besafe on the rods out there.  I have seen some the dash cams of accidents; some crazy driving going out there making it more dangerous for bike riders.

Thanks, Aaron. In 2006-2007 you were the person who inspired me for swingarm integration :)

My polishing master is like a drug-dealer. I made polishing by myself long time ago.
When I got my cb-1 back I had gave him one part for polishing.
He made it and I had compared his polishing with those parts that were polished by me.
Then I understood that he had caught me and I am on a needle...

Velos,

Thank you for keeping your thread updated with your progress.  Your passion for the old bike we ride is very inspiring.

I am interested in what compression and rebound shimstacks you will be running on the rear shock.  Will the RT shock piston allow you to run both a high and low speed stack on both sides?  If so, would you mind posting what you went with on each stack?

RT have tricky schema of valve supply.
1)  You should choose your bike's model and weight. RT will give you a necessary kit.
2) After you get the kit you should enter one-time code with your weight, style of riding, etc. This will give you a specification codes (cL, cLX, cH, rL, rLX, rH).
Using a chart from the kit you will get the shims sizes and their quantity.
This stack includes both low and high compression and rebound shim sizes.
Do you want to know those shim sizes and their quantity?

Also, I am interested in your experience with the aftermarket ignition timing setup.  It looks like you will have some interesting adjustability for a modified powertrain.  Are you changing lobs on the engine cam?

I am changing camshafts. I am using NC23 cams.
Dyna2000 is fully adjustable and can be programmed to any timing.
I plan to start with stock NC23 timing. Then I will correct it based on dyno run result.
But there is some kind of magic with Dyna programming.
I was asking Dynatec support about difference between programming Dyna with two different pickup sensor positions and they say that it doesn't matter...
I always should enter final needed advance in CurveMaker. But both Dyna and CurveMaker don't know about physical pickup position...

Looking forward to your thread.  Also, besafe on the rods out there.  I have seen some the dash cams of accidents; some crazy driving going out there making it more dangerous for bike riders.

Hello again.
Project is moving forward.
Slowly, but surely.

My N2O kit includes AFR gauge.
It can't be used "outside" due to it is not water-resistant.
(https://pp.userapi.com/c837725/v837725541/386f1/_w6nnamz8ZA.jpg)
(https://pp.userapi.com/c837725/v837725541/386e8/xba2rCfOqgk.jpg)

To make it water-resistant I first found appropriate O-ring.
(https://pp.userapi.com/c837725/v837725541/385fc/y32Y_rEga_8.jpg)

Next step was developing it's new body.
(https://pp.userapi.com/c837725/v837725541/3860d/wC1LrA7oZzw.jpg)

Next step: to make appropriate polycarbonate glass.
(https://pp.userapi.com/c837725/v837725541/38616/3x0wXQjWRdI.jpg)
(https://pp.userapi.com/c837725/v837725541/3861f/vT-EG4GWeqY.jpg)

Here is the final water-resistant body. I will make a mount later.

(https://pp.userapi.com/c837725/v837725541/3863a/MdrM40ilyDY.jpg)

Meanwhile I am working on adapring FCR.
There are no special o-ring seals available on the market for air-filter adapters for FCR32.
I have found usual o-rings (petrol-resistant) that have fited.
Also I have missed with BMC filters: I had to order new set with offset. When they were without offset they had a contact with each other when being installed.
(https://pp.userapi.com/c837725/v837725541/38643/cBci8lh7Wg0.jpg)
(https://pp.userapi.com/c837725/v837725541/38654/RqVF_VoZBl8.jpg)

Engine assembly is nearly completed. It remains to tune ignition timing for Dyna2000. It is not a trivial procedure.

One of my ideas was harder to perform than it seemed: ass modification.
It was rather easy to cut it off but to make a new one was much harder :)
Here are some photos of intermediate stages.
I keeped stock undertail. Seat lock was moved. Seat will find it's new cover soon.

It will add additional HP by increasing ammont of burning air/fuel mixture :) (like any other method of power increasing).

And have you done that before on another bike or is this an experiment?
No, I have never done it before (but I always wanted to do it :) )
It some kind of experiment/fun/self-education/dream/madness/etc.
I have wrote in my first or second post:
"There is no any common sense in this project. There is no goal of money saving (I don’t want to make even a preliminary estimate of the total cost).
I like this bike. He is dear to me as a memory of my father from one hand.

What does "GLW" stands for? I don't know this acronym :)
As for fireproof: it's a common mistake about N2O.
It is not flammable itself. Moreover during N2O reaction inside cylinder you will gain pure nitrogen, which in turn reduces temperature inside cylinder.
The only risk is high pressure bottle on the tail... But you already have shock reservoir, tyres and pressure inside cylinders :)

Stay tuned, I hope I can post the results soon!

Love what you're doing here but I've got a few questions.
Any reason for not using stick coils? (would take up less space)
How are the NOS injectors held in place on the rubber inlet manifolds? (normally they are fitted into a threaded hole)

Good luck with this and can't wait to see the end result

Spark becomes a “weak link” when dealing with N2O.
Therefore it should be stronger. Stock coils have a known problem of weak spark when using N2O.
In addition to this I need the space where stock coils were for installation of additional fuel pump :)

Those Venom injectors have a special retainer for installation into rubber manifolds.
