Troubleshooting Rear End Drag

Post by sphen » Fri Nov 22, 2019 1:26 pm



(this isnt a weight loss question :roll: )

I'm working on the non-functioning (yet) project bike. When I roll it in the garage it's dragging, with some friction noise in the back. I thought maybe the brake was stuck, but i removed the caliper to no avail. So I'm wondering if perhaps it could be 1) stuck in hi gear and free enough to roll but resistant, 2) the clutch is messed up (the lever/MC is indeed non functioning at the moment so i dont know if it is engaged or not in the case), 3) the final drive is half stuck.

Any thoughts?

i don't have electrical all hooked up yet so i cant tell what gear i'm in; i thought i had found neutral, but i'm not real sure yet.

Put it in gear and see if it locks up. That would eliminate a few questions. My guess is just a lot of gummed up stuff that will take care of itself as you clean it up and get it going.

Does not lock up in gear.

Presuming the clutch is staying disengaged..

Will try to disengage the final drive at the rear wheel - to test if it rolls freely that way

I would agree. Just not sure of how the clutch would freeze up in that position, but I guess it's possible. Maybe a broken spring retainer plate?

I got the LCD dash hooked up enough to display gear position, so I verified it was in gear.

But that led to another question - as indicated, I can shift N-1-2-3-4, but not 1st or 5th. I don't know much about these bikes - does it prevent shifting to 1st without the bike running or some other factor? Or perhaps something else is awry?

I'm slowly solving pieces of the puzzle though..great fun LOL. The starter relay is disconnected - my next move is to get the starter switch working enough to turn the motor over..

My 1200 has a bit of a problem when it has been parked and cooled off. First gear is hard if not impossible to shift into or out of. If I rock the bike back and forth it is easier, and if started (with the clutch pulled in) it is easier. Could be just that. Once running and warmed up it is fairly easy!
