Oil in crankcase

Welcome Dan,

In regards to your reed valve. It's not a positive seal so there will always be some oil under the crank after it's been sitting for a bit. That's why when you change the oil, after the majority of the oil has drained out, you have to be sure and kick it through several times while leaning the bike a little to the left, then when you lean it back over to the right, you will surprised how much more oil comes out. In fact, on one of my rebuilds on my 94 501, I had the shop weld in a bung for a drain plug right under the crank so I would be sure and get all the oil out.

The old style breather system also did not have a drip tube so to speak like the newer bikes so oil in the air box is quite normal. Also, the older bikes like yours do use oil I think because of this, so if riding for a long time, be sure and keep an eye on the oil level.

And speaking of oil level, you say you checked it and it is not overfilled. Very respectfully sir, how did you check it?

When you say the bike smokes a lot, could you give us a little more specifics? Have you ridden the bike very much, or have you seen that just from starting it up at home?

Be sure and visit the "Owners Doc!" for a good overview of these bikes.

welcome dan!

i think you should treat that engine to a rebuild don't you?

i would think the linar is worn and scored. mechanically you can still get most things.
