Message: [QUOTE="youngnbald, post: 1322668, member: 98329"] I am new with the dirt bike scene and looking into checking out my engine on the 2003 CRF450R. I bought it used and it wasn't ridden much. I do not know how many hours are on it except what I have driven now. I have read that the intake valves are better if they are steel and a good piston is the Wiseco. Should I just go ahead and replace the valves and piston if I am going to start looking into checking the engine over? The bike starts fine cold and never a problem restarting once hot. I read people buy the top end gasket kit and they say not all gaskets are there. What should I be buying and from where. I found the piston kit by Wiseco online and Faction steel intake valves with heavier springs. I have read to just replace the rings after 20 hours. What am I missing here? Recomendations? I looked at Service Honda but thought rockymountainmc was a better site. Where else makes buying parts simple online. [/QUOTE]
