the shop wont fix my quad cuz it has 2 much rong with it. but one thing they sid is that i burnt out my cam shaft cuz they sid i must hav ran it low on oli to long. but i actuly have the oil tank over filled. i never heard of burning a cam up. so waz up how did i burn up the cam. or what happend to it. its still drive able. its a 400ex 100% stock engine except for the clutch.

 

You cant nessesarly "burn" one, but you can ware the **** out of one.

 

can u tell if its bad by driving the quad? it hasnt been pulling wheelies as good no more.

 

what if i dont change the cam?

 

running to much oil in any engine causes the oil to foam or bubble, thus reducing any lubricating qualities.

 

i dont have my tank filled way to much. its just slightly over the full mark. and whats the best cam to put im a 400ex.

 

i would have to say stock for best reliabiity
