i have an f4i and i installed the 900rr idle cable. i ran it out to the left side between the frame, airduct, and tank. at first i had no probs at all. i could adjust it as high as i wanted. now, sometimes it moves easily but usually it feels like it binds up and wont turn. if it does turn it usually takes alot of twistin and then it kinda pops free of the bind and jumps up a few rpms at once....i might try to lengthen the cable to run straighter aproach from the front of the tank....any better ideas....maybe just lube the cable?
