Unless you learn to do your own maintenance on a dirt bike it will literally eat you out of house and home. Valves need regular checking. Too tight a valve can contact the piston crown and when that happens you are looking at serious costs.

Just follow the instructions in the manual exactly and you should be fine.

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.

The problem is that those 4stroke MXers have the same extremely light components that you would only find on works bikes in the past. They simply wear out very quickly. The only solution is to either get a 2stroker or one of the less extreme 4strokers and live with the reduced hp.
