Well guys. I have a 2005 kfx 400. It had a bad top end tick to it so i put a brand new DID timing chain in it. The valves are all in spec, and the cam timing is right on the money. It is still ticking really really bad. I also have all new head gaskets and low hour cylindar and piston out of an 06 z400 that i put on when i was doing the timing chain. So it has to be somthing in the head. It runs really good other then this nasty tick. Any ideas? id really appreciate it. Thanks.
