[QUOTE="Oldhaven, post: 70668, member: 2879"] To fill out the story of my V3 clutch drag problem, you may remember that I had done several things that seemed to help incrementally, using a dial indicator on the clutch center button to measure lift at each stage. Swapping springs around and shimming them, getting the new G91 lever, careful adjustment, filing the slots for clearance, and a few more things that you all suggested all seemed to help. Weather shut me down for the year but I had gone from .053 of lift to .062 or so, for some improvement, but I had not gone on any long rides to get things really hot and test my lift improvements. I just got the bike out for spring, and during the winter I ordered a Motion Pro longitudinally wound cable, as davidd had suggested. Not one to give up on a step by step plan, I remeasured the clutch lift with the old cable again and somehow over the winter it had lost a few thou and was down to .059. Not what I had but still better than .053. Fitting the new cable required some fettling since MP did not have the exact fittings required. I had to ease the inside of the cable abutment at the clutch end to 5/16, and file the cable end just a bit so it would go all the way to its seat in the abutment in the G50. The new cable after tweaking the adjustments again is giving me .068 lift, so a definite improvement over the spiral wound outer original. I went for a ride and all went well, but I still have to do a long one before I feel OK about things. in Mid Winter I had sent the valve lifter cable to MP for an example and while removing it with the bike under its cover I heard a "tink" and my knurled cable abutment for that cable was no where to be found. I kept that in mind since I suspected it was in the chain recess and something in there can ruin your afternoon.
