I wouldn't want to steal this thread but...
Yesterday I tok the bike,m which I thought to be without much oil in the sumo, and looked through the little view window.
Nothing - pitch black. Assuming this meant there was no oil, I topped up, little by little, until I eventually realized I was topping up a good three pints (!!!)
Topday the bike started but is very lazy.
She will NOT rev beyond 4000 rpm (I have a tach) and sounds... thicker than usual.
Upon arrival, she was "smoking" oil vapors everywhere, I almost thought she was going to catch fire.
After some two hours I had an easy ounce pooled under the engine.
OK... have I overfilled? Is the piston laboring because of excessive crankcase pressure?
Can I make it home (I guess so...)
I plan to emty the cranckcase, measure the oil and refill two liters...
But, how can I clean the viewing window ?
