Ok I just got finished rebuilding my quad from the ground up. The start of some of my problems is keeping the bike at idle.I can get it to fire and run but am noticing a couple things, but dont know where to start to fix the problems........I notice the headpipe is getting hot very quickly within a minuet and also smoking where the tail pipe and header connect. (could be the clamp) I also dont run it any longer then i have to.......Afraid to cause anymore problems..... I also seen a small very small amount of coolant leaking from the water pump cover yesterday...but was fine today, The water pump cover was getting to hot also within a minuet.. It seems to have a smell when its running. I dont know where to start....radiator, water pump, fuel issue? any ideas where you would start, i just sunk alot of money into this build so im hoping to find an easy fix but thats never the case lol any ideas where you would start.
