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 Smiley

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.

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.

Thanks. Everybody should be safe regardless of their geo-location Smiley
It's cold here (+3 - +5). And I don't hurry to get on the road. I prefer to ride during warm weather )

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.



To make it water-resistant I first found appropriate O-ring.


Next step was developing it's new body.


Next step: to make appropriate polycarbonate glass.



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




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.



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 Smiley
Here are some photos of intermediate stages.
I keeped stock undertail. Seat lock was moved. Seat will find it's new cover soon.








One of my old wishes came true: kellerman LED turn-signal + load independent relay.

Did I read that right, you are adding a Nitrous Oxide kit to it!?

What will that do to it's performance when boosted, any idea?

And have you done that before on another bike or is this an experiment?

Hi!
Everything is right - this will gonna be a nitrous CB-1.
I have posted a kit on a previous page:
http://www.hondacb1.org/forum/index.php/topic,5290.msg25413.html#msg25413

It will add additional HP by increasing ammont of burning air/fuel mixture Smiley (like any other method of power increasing).
Quote
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 Smiley )
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 dont 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!"

uhhh....Nitros...? On a CB1?
right....be prepared to ride with a fireproof motorcycle suit at all times.
GLW that.

Make sure you capture it on video when you take your first flight.

What does "GLW" stands for? I don't know this acronym Smiley
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 Smiley

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

I believe Velos is only in danger of being regarded as Galilei and Serventos here...! This is brave advanced work. Let us hasten only to light the fires of enthusiasm and encouragement!!;)

In sure the artists, philosophers, poets and crazy ones will get what he's doing, as well as what I'm saying. As Bill said, It's just a ride.
