Hello, I need help with figuring out what’s wrong with my raptor. I just rebuilt the top end because it had no compression the piston Was really worn. I put a 686 piston kit in it, and put it back together followed the service manual. When I started it it started just fine but started getting hot quick I hit the gas and it revved good, then I hit it again and it started popping and bogging. Not sure what is wrong with it has a new spark plug and well a new piston everything else is stock carbs are clean, could it be the timing chain, maybe valves? I did adjust the valves to spec and turned it to check again all was good. It does make a suction kind of noise every once in a while and has a slight ticking noise. I adjusted the timing chain like the service manual said too, not sure what else to do. Do I need to adjust the carbs? Any input is appreciated thank you!
