Hi, all--been a while since I've posted...hope everyone's well.
Finally had a nice exhaust made up for my bike, replacing one I welded up with some guys in a shipping container in West Africa.
But with the change has come white smoke coming from the junction of the head and pipe, and oil spray on the front fender, downtube, and header. Smells like burning oil, too. I think, frankly, this may have always been the case to some extent, but the pipe wrap I had on the old exhaust (to hide its ugliness) mostly absorbed it. Took the pipe off and there was oil all over the shim encircling the pipe and the port itself.
This could only be coming from the rocker box, via
1) a crack
2) a bad valve guide
yeah?
Bike runs fine otherwise.
