New 05 CRF 250R Shim question

[crmx0312]

My CRF has like 30 minutes on it (bought end of last season). Anyway i checked the valves and got 004 right int .005 left intake. .010 left exhaust and .009 right ex. Should i shim the one ex valve now or wait? Like i said the bike is new. And if i wait should i wait the 15 hrs to check again or check them sooner. Thanks

Shim it, better safe than sorry. heck it only takes a few minutes. :yikes:

shim them. They settle after brek-in.

Wait till you get some time on the engine and check them again. it's also worth getting yourself a good metric feeler guage so it will be easier to relate clearancesa to shim sizes.
