I've got a 1998 Formula 3 700 and my primary doesn't seem to be shifting out all the way. I'm not really sure how far from the top the belt is supposed to go, but I put a marker line on it, and there was still about 1 1/4 of an inch left after a wot run. The sled halls a$$ up until about 80mph then just kinda quits. I've pulled it apart and cleaned it, tried again, and its the same. I can see were the arms stop on the ramps, but the rollers in the arms seem to be ok. The secondary is shifting out all the way. Could the primary spring be bad, and binding? Any help would be greatly appreciated.
