Whats going on Guys and Gals, I have been on here before with a few questions about my Foreman 400. I tore in to the motor replaced the timing chain, bored the cylinder out .25 new piston, rings, valve seals, ect. The problem i am having with the quad is that it will run and start great however when idling it will knock about every 15 - 30 seconds and sometimes die right when it knocks at low idle. It will start right back up again. I have placed the T and checked the cam to make sure the dot lines up with the arrow inside the case. I adjusted the valves, they sound good not ticking. the knock every 15 -30 secs will stop when you are above an idle. Any Ideas?
