Ok so i just got a 01 raptor and i went through the bike and when i went to ajust the valves the intake were fine but the exhaust were tight. I thought it waasent ad TDC so i turned her over and checked again to be shure and i was at TDC so i ajusted them out and when i went to start it would turn till sompression stroke then stop. So I took it apart and turned the ajusters till they touched the valve and locked them in> When i went to start her she started right up. My question is what could cause that? Bad valves? Nees a valve job? something worse?
