Please help me I just bought an 04 yz450 and its my first 4 stroke. The second day I had it out the kick starter broke on the first kick but it started on the first kick also. broke the gear inside and chipped the case so Yamaha warrantied it and had to put new case halves in my motor. 3 weeks later I finally got my bike back and there were bolts missing and hose clamps not tightend down and I was VERY angry with my dealer. I got it started after several kicks and rode it around for 5-10 minutes then shut it off.. about an hour later I started it back up and it was idling warming up a little and it died and I havent got it to start ever since? Are they really that hard to start or did the dealer do that poor of a job that my motor doesnt want to run now? Any info would surely be appriciated.
