Hey whats up I own a 05 450r and just had it rebuilt. after an hour of riding it a valve dropped and bent the valve. A local dealer told me i needed heavy duty springs with my hot cam. so i put new springs and valves in it and now it won't start. I'm getting fuel, spark, its in time, its shimed right but it still won't hit. It doesn,t even try. If anyone has any suggestions i'd really appreciate it thanks.
