These are all the valve shims available for the CRF. The shims are marked in mm but they are rounded to three digits: 1.825mm is acutally 182 on the shim and 1.875mm would be marked 188. As far as the measurements in inches, I carried them out four places. If I would have rounded them, you end up with two different shims with the same english measurement. Must be the shift between the two standards I guess. RR.

thanks fred, I noticed the intake shims have numbers on them, dont want to guess, but do those numbers equate to the actually size...

R. intake had a 62 on it, L. intake had a 68?????? Mine only have a two diget number, maybe the one is worn off??

just want to get a baseline where to start when I reshim?

Yes, sounds like the 1 is worn off. It's probably 1.62 and 1.68.

Worst case bring them to the shop and have them measure them if you don't have dial calipers or a micrometer.

I got it figured out,


162=1.625, the one was worn off.

I was making it more complicated than it needed to be....

Service Honda doesn't have any shims bigger than a 2.45 so if you need anything that big or bigger, go to Webcam for them. I recently installed an RHC 208 Web cam in my bike and it required 3.00 and 3.05 shims and they make them up to 3.50 I believe. :cry:
