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.
4  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.

Sorry. I forgot the pictures. Pictures have been added.

JamesM, Thank you for your reply. Good to know regarding the Diablo Rosso II's.

I went out and looked at the current tires that are on the CB1. Currently the front tire is a 110/70R17. They are Pirelli Diablos radials. The rear tire is a 150/60R17 Pirelli Diablo radial. What is the physical size difference between the 150/60R17 and the 140/70R17? I believe the 140/70R17 will be narrower and taller.

I took a couple pictures of the tires. Am I reading the DOT date codes correctly? The front tire was manufactured on the 45th week of 2004 and the rear on the 10th week of 2004?

Hello everyone. I recently introduced myself here, and as some of you know I recently purchased a CB1. I have been doing some reading regarding tires choices. My CB1 has good tread on the tires but they are very old and hard. Time for new tires. I have read quite a few threads but some are quite old. I wanted to see if anyone has any updated recommendations regarding tires for the CB1? From what I have read, I believe I would like to stick to the stock tire sizes. Here is what I am thinking so far.

I will be using the CB1 as a weekend motorcycle. I will not commute on the bike. The weekend rides will be spirited with a mix of straights and twisties. I would like them to be sticky and confidence inspiring.

I am not overly concerned with mileage since I will not be using it for commuting. I doubt I will put 1,000 miles on the bike this year. I do not need a tire that last 10k miles. 

I had a set of Pirelli Angel GT's on a Triumph Speed Four in the past. They were great tires. They were classified as a sport touring, and they did everything I wanted them to do. They felt sticky.

Here are some options that I have come up with for the CB1

Bridgestone BT45 - Quite a few people seem to like this tire on the CB1, but most seem to be concerned with tire life and mileage rather than performance.
Pirelli Diablo Rosso II
Pirelli Sport Demon
Bridgestone BT92 -I believe these are not available in the USA
Bridgestone BT-090 - I believe these are not available in the USA

Does anyone have any comment regarding these tires or any other suggestions? I would like to get the best deal out there. I do not need to spend big $$ on tires if I don't have to. Thanks.
