Just a thought here, but you might think about the U-joint again,
perhaps it's binding only while under torque. You could use the old big
screwdriver to the ear trick and poke around listening for grinding
noises around the swingarm tunnel if you can get it to vibrate while
running on the center stand. Maybe pull the plugs, put it in 4th gear,
and rotate the whole thing with a big socket on the generator pulley nut
while holding on to the rear wheel, and listening around for funny noises.
This will probably take 3 people, which sounds like a party and an
extra 6-pack.

| Clutch operation is smooth but when I had the bike on the center stand...running...and engaged the clutch the rear wheel would spin but there was a definate binding as the wheel turned. Could my problem be with the rear drive unit? Ed and I pull the rear wheel.....rotate the rear drive with no binding whatsoever. We run the bike....engage the drive and it is smooth also. Wheel bearings rotate freely....brake pads/assmebly is nice and tight. We remove the top plug on the rear drive unit and look inside. The gears look perfect. No metal shavings...no sign of wear. Binding is intermittent. Weird. |
| Ujoint. When the bike is in neutral or gear engaged with clutch lever pulled the wheel rotates smoothly. Weird. I finally said screw it and decide to ride back with Ed a ways. Rode back and could feel vibration at about 60mph. If I pull the clutch in...vibration stops. Engage the clutch vibration comes back. OK....so the problem is in the clutch I figure. Maybe the tranny? Time to pull the engine again and be thankful that I have backup rides. Looks like a call to Mark is in order....possible replacement of all the clutch components....I mean everything? I still can't figure this out. It is like nothing I have ever experienced and one would think that this kind of problem would be easily identifiable and fixable. Of course I will report anything learned and would appreciate any further thoughts. ...Ian |
