Motorcycle Repair: yamaha dt 175 1978, yamaha dt 175, clutch side

Question
its me again one more ???..   I recently change out both crank case seals right and left and the bike still smokes excessively it also has a new piston and rings.  What could be causing this.

Answer
Wayne,

-are you using the yamalube injection system or premixing
your gas/oil? The cable can be adjusted on the
yamalube to open later.
-If your gas/oil mixture is okay
It could be your exhaust pipe may be clogged with
oil and it is burning it off. Unfortunately
they need to be cut open, cleaned out and
rewelded.
-Is the transmission fluid level going down
at all? keep a close watch on it to see
if it is trans oil or not. Make sure
it is not overfull either.
-When you installed the new seals did you
notice much wear on the crankshaft ends
or possibly loose engine bearings?
-Loose bearings or shaft wear may cause
the clutch side seal to leak.
