This weekend I took my yfz450 out into the shop and adjusted the valve clearance along with doing the cam mod. All went fairly well and we had no incidents putting it back together. Now After we got it finally started and warmed up I took it out for a test ride. I really noticed a improvment in the bottom end like many say and thought cool. Get back to the house and look down.... there is oil coming out around the head gasket, oil filler cap, oil cap on the crankcase, the oil line going into the resivior, the return line in the vale cover. EVERYWHERE!!! [img]i/expressions/face-icon-small-sad.gif[/img] does anyone know what is wrong?

 

Sounds like you might of over filled it. Hows the oil level now?

 

Well we figured it out, it was a rubber seal on one of the screws holding down the valve cover. WE put it back in and problem solved. Next thing is to figure out jetting for the mod? w/ a k&n filter what should I use for a different pilot jet? It doenst idle very well and is hard at starting.

 

Have you tried adjusting the idle jet that you have?

Generally inbetween 1-3 turns is where you wanna be.
