When I picked up the bike, I really had to muscle the rear lever to make it shift. I loosened the tension screw? and now it shifts easier but now it shifts itself. I pulled the cables out of the housings and lubed them (seemed smooth). I'll clean up the shifter guts (it is friction shift) and see if that helps. If not then I have some other shifters floating around (suntour ratcheting) and see if that'll work. Btw, the original setup on the Fuji is suntour AR.
