oil out of exhaust

[mabell1618]

I had a nice 1hour ride yesterday, and this afternoon I noticed some oil dripping out of my drag pipes on my 72 ironhead. Never seen that before...any guesses??? Thanks!

Valve Seals / Piston Blow by one of the 2 i would guess how did it run .. smoking as it ran?

Valve Seals or worn rings. Take a compression test and do a leak down test.

several guesses ---- Bud & Glider has mentioned the first steps. How low on oil is your scoot??? Did you add any before you took off??

no smoking, and purred like a kitten..

Typically there are no valve stem seals installed on Ironheads.Not enough room.You have excessive clearance on the exhaust valves.Time for a valve job.The reason there's no smoke is because the oil is coming out after the combustion chamber.Easy to diagnose.Just pull the rear pipe and look at the port.Nice and wet with oil.Won't show on a compression or leakdown test.
