Oil Spitting Out Spark Plug Threads And Pipe

[jasonsb]

I've had this problem for about 6 months but it's never really hurt performance. I thought I'd just see if anyone has had this happen:

 

Oil is spitting out the spark plug holes. the spark plug threads are always wet but the plug tips are fine. Also, oil spits out the right side pipe where it connects to the jugs.

The cool head had new gaskets and the pipe has new o rings. It doesn't hurt performance but it makes a big ass mess every time I ride.

 

ANy help ou there?

Try coating the pipe o-ring with some hi-temp RTV (silicone). And mine does the same thing with the plugs unless they are tight; try fresh plugs (the metal gasket crushes and may or may not seal right after being tightened once) and get them tight...just don't torque the hell out of them and strip the head...something like 1 full turn past finger tight. Good luck.

What kind of pipes are you guys running?? I've never seen that....just curious..

I posted the first topic:

 

I'm using PSI pipes. They are decent. I've had fmf and PSI are way better. I'd say they are similar to Toomeys. I rarely see anyone using them. PSI is a snowmobile pipe maker. They are shaped like CPI but skinnier.
