1  General Category / Tech Corner / Identify These Front Forks? - Honda CB1 on: January 02, 2019, 07:00:19 PM
Hello, Can someone help me identify the forks that are installed on my CB1? I believe these are either F2 or F3 forks. Is there a way to tell if the fork tubes are the original CB1 tubes or if they are different? I would like to get the forks serviced, but I am not really sure what these are.

Finding a Ontario Moto Tech/Sudco exhaust, is like hitting a lottery have a chance it you look but highly doubtful you will find one...

I totally agree. I have been looking for one for years. They just do not exist.

This truly is an amazing find. I personally hope that it ends up in a museum where it belongs. Its beyond perfect. If its in a museum then maybe there is a chance I will get to see it one day. Good luck to anyone here who might be bidding. Only a few hours left and the reserve has been met.

No no luck yet. I am ready to buy if I can find one.
7  General Category / General Motorcycle Discussion / Stuck Gas Cap - New Replacement? on: January 20, 2018, 11:20:51 PM
Hello everyone. As some of you know, I have a few different CB1's. I purchased a parts bike a while back. It did not have a key. A locksmith tried to pick the gas cap lock, but it was frozen solid. We ended up having to drill it out. You can see all the corrosion on the underside. I thought someone here might find the pictures useful. I now need a new gas cap for this tank. Does anyone know if one of the Honda universal "racing" style caps will work? I attached a picture of one that I am looking at. Thanks

Hello Everyone, Does anyone have a picture of the SUDCO full system mounted on their CB1? I have seen plenty of pictures of the Kerker exhaust system, but not the SUDCO. I know the SUDCO version is pretty rare, but I wanted to see if I can get a picture of what I should be looking for. Thanks.

I found this exhaust on craigslist for anyone who is interested. I think it actually is the CB1 version.

Thanks everyone. I agree. The change has changed the final gear ratio very little. Can someone explain if any difference would be felt in a 16/40 gearing and 15/37? Since the final ratio ends up being almost the same, why would you choose one over the other? Any performance difference?

What RPM do most of you see at 65mph on the speedo?

Yesterday I had a set of new Bridgestone S20EVO's fitted to the CB1. So far so good. I went back with stock sizing front and rear. The tires seem to heat up quickly and felt very planted. Here are a couple pictures.

Well, I finally got around to making the chain and sprocket change. I have attached a few pictures of the swap. The bike had a 525 chain with 16/40 sprocket setup. My goal was to go back to stock gearing and try to reduce the RPM's slightly at cruising speed. Based on recommendations I went back with a 15/37 setup. It looks like the gearing did not change much though. I went form a 2.50 gear ratio to a 2.47.

On the way home I saw 64-65MPH on the speedo at 7k RPM (I have not checked this with GPS speed). How does that compare to others? I am wondering if I should of gone with 16/37 which would of brought the ratio down to 2.31.

Can anyone explain the difference I should of seen/felt by going from a 16/40 to a 15/37?

Hello everyone. So I am just now getting around to getting new tires for the CB1. I think I have it narrowed down to two different choices.

Bridgestone BT45 - $250 for the set

Bridgestone S20 EVO - $200 for the set

I know that the S20 EVO is a stickier radial tire that will not last as long as the BT45. One normal roads with pot holes etc, will the tires ride any different? One thing I noticed is that it appears that the sidewall on the BT45 is much larger. Is that true or an optical illusion?

I do not plan on doing any track days with this bike.  Thanks for the help.

VintageHunter, Good idea. I will plan on doing that.

Hello again everyone. As some of you probably saw I made a post a few days ago regarding new tires for the CB1. While I have the bike apart I thought I would change the chain and sprockets. I am unsure of the last time this was done so I thought I would do it now. I did some reading here and it looks like the stock gear ratio was either 15/37 or 15/41. Currently the rear sprocket appears to be a 40 (picture attached). I am unsure of the front sprocket size. Being in Texas we have mainly straight roads out here. We have to ride quite a ways to get to the good roads. Having a gear set that was suited to straights and highway riding would not be the worst thing around here. I do no want to sacrifice too much performance though. Can someone help clear up what the different gearing choices would do? I believe a 15 on the front sprocket is really the only option. I have not heard of anyone changing that. Can someone help me decide between the 37/40/41 rear sprocket?

What chain size will be needed? I believe the stock size is a 525 but I am unsure of the length. Thank you.
