I was so interested by your thread that I bought a K750... did not want the sidecar (I have a GU Ural) but really wanted a SV! Did all of 50 miles with it! Gearbox was hard to change gears, front of the shaft was almost off the hockey puck and rubbing the frame/swing arm.... After looking at the gearbox rebuild here, I decided I was better at polishing paint and bought a "new/redone" gearbox on Ebay (motowadimus).... the only thing new were the outside bolts/screws. The inside was in worst state than mine!! So now the gearbox is out to Ken Ulrich... Gearbox turning into dearbox!!
