2007 sawtooth
 

Hello,I have a sawtooth 200 i just went through and since i put a new piston in it starts just fine but has a drum drum drum sound that i just can't figure out. I rebuilt the carb,rechecked the timing did everything i can think of. Is there anyone out there that can shed some light on this problem PLEASE? Rocky

That sound can be from anywhere,timing chain,clutches,etc... If you could post a video on the noise.
