valve specs on 06 crf250r

12 posts in this topic

My 2006 CRF250r measures as follows:

R intake = 0

L intake = .005

R exhaust = .009

L exhaust = .009

Can someone tell me what size shims to install?

Thanks!

Never mind . . . I'm learning and realize I need to get the kit, then pull it apart and use my micrometer!

Thanks anyway!

You need to see what size is in there now and then go down until you get clearance, then adjust the correct clearance. You won't know what shim you need until you have clearance.

Ok. Let's say I'm gonna shim.

I take a measure. Then, I remove the existing shim and measure it. Then I subtract the underage from the existing shim and select/install a new shim. Ok.

How much assembly do I have to perform to get a new measure? I mean, do I have to torque everthing back or can I lay the cam in there and get a quick and dirty read?

I'd throw the cam on there and then atleast snug it down. With such little tolerances the difference between tightening and not tightening could cause a difference.
