I have a major issue with my 06 CRF450R with it not wanting to start up. Its got compression but it takes like 15 kicks for it to start up. Then when I do get it started and ride around for it to warm up a bit it shuts off when I pull the clutch in to keep the motor running. A buddy of mine and I took the head off and checked the valves with a feeler gauge. Im not too familiar with motors on dirtbikes but looking at the dirtbike from the back to the front. My left valve is at .005 and my right is at .001. We guessed that because we couldnt even fit a feeler in there to know what it is. I need help on what I should do. Take it to Honda and pay a but load of money to get it fixed or try it on my own with my buddy by a manual.

Thanks for that reply man i appreciate it. I have two valves I checks my manual that I have at home. I knew my motor was at top dead center because all the marks were lined up correctly that the book speculates on. Im taking my bike to a Honda shop by me and they're going to check it out. Im hoping that its just reshimming the valves and Ill be on my way. I wouldnt think Id have this problem because I change my oil every three rides religiously along with my oil filter and I clean my air filter and air box every two rides. So this really has me dumbfounded.

Yeah its got just about 30 hours on it your right. Man a full topend rebuild is not what I want to do. Im hoping just reshimming and adjusting would work out.

I took my bike to Honda and they shimmed the valves to proper clearance. However soon I will have to replace my intake valves or I will lose power. Im going to look for those Stainless Steel valves you mentioned. Thanks buddy
