Greetings,
I have not be into my 72 interstate engine. The engine is a combat, has the crankcase vent on the back of the engine.
As we all know these bikes wet sump if allowed to sit for any length of time. After a few days of setting the oil level drops about a 1/4" on the dip stick. I start the engine, then shortly the oil is being forced back into the tank.
I assume it is just the crankcase pressure that is forcing the oil back to the tank? With that being said, is there a point to where there is too much oil in the crankcase and not enough pressure to force the oil back to the tank?
I've owned the bike a couple of years, and have drained the oil when riding season is over both years.
I'm not going to install anti-wetsump check valve, I'm just curious how long it could sit without issue??
Thanks for all replies.
