i have done the break in ride on my new 09 crf250r. WOW, I love this bike, there is nothing i can say bad about it. I checked my valves after the one hour break in and this is what they are: intake-.005 exhaust-.010 I know they are within specs, but is there a reason that only my exhaust clearence tightened up slightly. I have been riding many years, but never on a race bike. My other bike is an 07 DRZ400. So any helpfull info that anyone can give me with regards to service, and or just owning a race bike would be greatly apprieciated.
