Hi Jeff:
I'm buying that nice Transalp you built and sold to Mark Sampson.
Fortunately, I have a good TA donor engine, so it should be a fairly simple job getting the bike back on the road.
Wondering about the cause for the rear piston going south. Is it possible, with the dual feeds from the AT tank, that somehow the rear carb was running lean or even dry, and the excessive heat holed the piston?
I would hate to install a good engine and then have a similar problem.

Would love to hear your thoughts.
