bad noise in motor?

sounds to me like it needs a topend rebuild. Thats what mine sounded like....I could be wrong though.... Good luck!!
 
mine is starting to kinda sound like that as well. I hope u find an answer so i can get mine fixed before it soulds that bad:(
 
yeah i went through and tightened the air boot a carb clamps adjusted the pipe and tighten everything and the noise stopped so i think it may have been an air leak
