What happens if the engine and tranny are not on centerline is that you turn the input hu and plate-spline interface into a planetary gear.

Patrick,
Thanks for the thoughts...yeah...I have thought about this problem being in the tranny. Didn't think about the concentric idea though. Maye something like the input hub gets hung up when the metal warms up?
Ed and I did take the back cover off the tranny last time the engine was out. Everything looked perfect inside. I was wondering if there could be a shimming problem though. At any rate the tranny is perfect when shifting and running. I'll pray to the Loop Gods that this isn't the problem :-)
I've thought a lot about this problem (especially as I am lurching my way through the city) .....and not sure what to think sometimes. I hate not having a logical solution and clear indications of where the problem is. Certainly all the indications lead to the clutch assembly but is that the symptom or the problem. I'll let y'all know after this weekend.
...Ian

Ian, I've been watching this thread for awhile. Not sure I have good news for you. I had a 73 Eldo with terrible hot-grab issues. I repeatedly did the clutch. Sometimes used bonded, sometimes riveted. Very frustrating as the bike was apart more than utilized. I was finally able to get another 74 transmission and my problems mostly went away. Guzziology talks about this. Because of all of the big, moving parts in the clutch, the transmission and the engine cases must be absolutely square and concentric with each other. They are not made as mated pairs. One part made here by Luigi and the other part made over there by Sergio. Apparently some sets are imperfect. No amount of parts changing (except for engine and transmisison transplants) is going to cure those bikes. Luck of the draw. Mostly it is rare. In the meantime, a good bath in the bell housing with paint thinner or mineral sprits (no, not laquer thinner or gasoline) can do wonders for about 1500 miles. Just a short messy evening job once a month.
