Thanks for sharing your experience and knowledge...I just rebuilt this '88...forks are stock and work pretty well for me with Honda HP 5wt oil...not, the recommended Honda ATF. I look forward to doing some of the tuning mods you guys are using to get

It says the Moose Racing Hardparts 0450-0269 fork seal and bushing kit is compatible with the '83 CR250...I think I'll order the kit and try them.

I just bought some from CMSNL...looks like they have both OEM fork bushings in stock.

Thx...Its going to be a weekly track bike...probably more modern tracks than Vintage tracks. The cases are powder coated. The alum finish on the cylinder is the result of the PowerSeal USA cleaning process. The head has a mild (muriatic) acid surface

Thx! I wanted to do this one a bit different...its still an old school looking racer with fork boots, but the black rims make it a bit more contemporary looking...then, it just seemed to me that the black fork boots work with the black rims...in place ... more »

My '83 CR250 and CR480 use the same carb insulator...even though they have different size carbs. The stock Keihin 36 mm and 38 mm carbs have same outer dia at carb insulator interface.

From what I have seen, the upper triple clamp on my '83 CR250 and '88 CR250 could be the same...they have hard mounted bars that are centered behind the steering stem...makes the bars feel low and close compared to a modern bike. My '83 CR480 top triple ... more »

The stock 36 mm Keihin carby can work fine. Stock: #160 main Pilot: #75 OEM is jetted for sea level altitude and 20:1 pre-mix ratio. I ride at 1000-3000 ft elevation (PHX and Tucson) and use 32:1 premix so the stock jetting needs to be leaned out. I've

I've been 'racing' a '83 CR250R. Last season, we had 125, 250, and Open classes. This season, it has been consolidated to 125 and Open classes. So, my 250 gets 'scored' against CR480s getting the hole shots. It would be easy to complain and get frustrated ... more »
