:nixweiss:You guys are making us cry. Abby's bike was smooth as well but it changed. Somewhere around $2500 spent and we still have not found and fixed the problem. The only parts not replaced that go round and round are the clutch plates, compensator and alternator. They were all disassembled and inspected for cracks, wear, chips, metal shavings, etc and appear ok. The entire engine has been totally rebuilt with balanced crank, new rods, bearings, pistons, pins, bored jugs, new rings, valve job and new motor mounts. There just isn't anything remaining that we can think of that will cause the nasty shakes. We surrender and will ride the bike as she is unless someone out there comes up with another idea.
Many thanks for your thoughts.
