If you can't find one closer to home then I have a 2nd hand one here in the UK. Also used on the NC23 version of the CBR400 (88-89)

Have you checked the main 30 amp (green) fuse mounted next to the starter solenoid?
Follow the wire from the +battery terminal if you're not sure where to find it and the fuse will be under the red plastic cap

Does the motor turn over on the starter? If so check the handlebar mounted kill switch, they are known to corrode up

As Aaron says try the All Balls or Athena seals, a lot of the cheaper seals on Ebay and some of the general suppliers are rubbish. Worth checking the bushes, if there are any copper coloured areas on the bushes, then they are worn and should be replaced

I think it might be your CDI - I had one recently which would be fine for a few miles and then something would overheat and break down. Once I got back to workshop and the unit had cooled, everything would be fine. Eventually you'll get to a point where the bike will start backfiring and refuse to start at all

Unfortunately it's the electronics that always let you down on these old bikes Sad
5  General Category / Tech Corner / Re: Are the NC23 (CBR400RR) carbs swappable to the CB-1 (NC27)? on: September 19, 2017, 08:14:38 AM
Did a quick check last night and the CB-1 carbs are VG04's whilst the NC23 carbs are VG06's.
What the exact difference between the 2 types of carbs is, I don't know but I suspect if you change the jets in the NC23 carbs to CB-1 spec then I can't see any reason why they wouldn't work well enough to get you out of trouble

By CBR400RR I'm guessing you mean the NC29. These carbs are completely different as they are a flat slide type and have different airbox fixings.

The earlier NC23 carbs are similar to the CB-1 carbs but strangely enough I've never tried swapping them over so can't say for certain

I've updated the photos on here http://www.hondacb1.org/forum/index.php/topic,2901.0.html so hopefully it now makes a bit more sense. Thanks for that Photobucket, it was a bit time consuming but it wasn't too hard to migrate the photos across to Flickr and update the links. I won't be updating the build thread as I think there was almost 60 photos on that one.....

I've started using Flickr for photos and so far it seems to work well and is just as easy as Photobucket to copy the BB code into your post. Just in the process of updating the photos in a few of my threads

I posted this a few years ago http://www.hondacb1.org/forum/index.php/topic,2901.0.html Unfortunately it has been ruined by photobucket but I will try and move the images to Flickr and update it
10  General Category / General Motorcycle Discussion / Re: "Neked" CBR F3 Cafe - I think it was nicely modded. on: September 08, 2017, 05:17:35 AM
I just don't get this whole putting 1960's style rounded seat units on angular 1990's bikes, the shape is just all wrong.
Now imagine that bike with a Cagiva Mito or Ducati 916 or late model Fireblade seat unit and it just fits in with the rest of the bike so much better.

that said the rest of the bike looks pretty tidy but I would want a bit more support to the rear subframe Shocked
11  General Category / Tech Corner / Re: Carburetor fuel leak on: September 07, 2017, 08:37:34 AM
It's quite common for the floats to stick open if the bike has been sitting unused for a while and all that is needed is a sharp tap to the float bowls to release them.
You can check the needle valves by turning the assembled carbs (minus the float bowls) upside down and blowing through the fuel pipe. If one isn't seating properly then you will hear the air leaking past it - or give yourself a hernia if they are all fine  Grin
12  General Category / Tech Corner / Re: Rain tyres for standard Rims on: September 01, 2017, 09:06:27 AM
The guys who race the 300 Ninjas with our club (BEMSEE) use Diablo Rosso's in the dry and Pirelli wets which are an odd size 100/80/17 front & 125/70/17 rear (it's normal for wets to be a different size to dry tyres as you want to spread the tyre for a better contact patch - or something like that was explained to me  Huh. The Ninja wheels are the same width as those on the CB-1

This is all getting very serious Dash, having 2 sets wheels, you'll be taking up racing next  Cheesy

14  General Category / Tech Corner / Re: Coolant hose kit? on: August 31, 2017, 06:28:12 PM
It was probably me who replied last time and yes the Samco hose kit for an NC23 will work on a CB-1.
 There are 2 thin hoses which go from the water pump to the oil cooler behind the oil filter on an NC23 which are not required and the hoses from the chrome outlets in the head to the thermostat housing need a bit of a tweak but otherwise all good

Only saw the start of the thread before any unwarranted language was involved but I have to agree, can we keep it CB-1 or motorbike related on this forum.

ModerateFK - you have been posting some pretty random stuff of late and hijacking a lot of threads. Your contribution is appreciated but please keep it relevant to the forum / thread
