Hi folks,

I have new heads and cylinders. The bottom of the fins on the cylinders seem to be accumulating a little bit of oil that I have to remove after each ride (one or two small drips if I don't wipe it down). I'm thinking I simply need to re-torque the head to the cylinder as a first step to see if that solves it? Any other thoughts around things I should be looking for?

Thanks,

Greg

I would check the tightness

I would check the tightness of the cylinders then re-torque the heads/ rockers. Adjust valves. I NEVER loosen head & cylinder bolts to re-torque. Make sure its not just blow- bye from the down draft tube in front.

Is The Leak?

Is the leak coming from the cylinder base gasket? If so, did you use Permatex Ultra Gray sealant? I didn't the first time and had to take both cylinders off and reseal with Ultra Gray. No leaks now.

Alternately, you might have a pushrod tube seal leaking. Are they squished enough?

Many thanks guys! It's not

Many thanks guys!

It's not blow by nor is it coming from the seal around the cylinder to the engine case. I think my first move will be to check the torque on the heads and see what that brings. Will report out on findings as I push through the process of elimination.
