Folk, please help with a pointer or two: I have just sorted my ignition with new pickup coils and was thrilled, but all of a sudden I ran into judder on pick up in gear. Revs fine out of gear. Had to slip the clutch a little in traffic and keep to get home a short about two miles. With a fair few revs goes a bit better. Heard squeal two or three times, when taking off in traffic. Prior to the coil fix, I had experienced what may have been increased judder in low gear in traffic, but nothing like this, which is incapacitating, and dangerous. I myself doubt gears, but being ignorant of these matters on the ducati, I cannot be sure where to start looking other than stripping out the clutch or rear sprocket carrier bearing (Of course, I should have a nicely adjusted chain)
I think you'll find that the squeal is coming from the clutch. The plates are probably just about shot....
Clean the clutch plates and check the stack height/hub clearance. There’s loads of posts on this subject.
