Well after having the bike for bout a year I finally couldn't take the single speed anymore so I got the SBP shift kit. I just got it installed and I kinda have a two question in one thread. One is the the grip shifters i have had 3 speeds in front and 7 in rear. Well the front was obviously disabled for the kit but its a pain havin the rear shifter on the same hand as the throttle. Did anybody else have this problem and what did you do? Second question is the chain from the jackshaft to the crank keeps loosening up. It's as if the motor keeps shifting but the mounts are tight and the tensioner between the frame and motor is tight. I've tightened it 3 times just today and i installed it today? Any ideas?
