High Idle Cure for Vulcan Classic 900
Not the same issue. The fast idle cam overrides the warm idle adjuster (black knob) during start up. In some cases the engine screams when it's just started. This is adjusted by means of the screw on the primary throttle shaft which is only accessable when the throttle is opened fully.
Well I got tired of the long high idle and looked into it. I found the high idle cam and decided to modify it to fit my needs. Since I live in a warm climate I didn't need the lengthy warm up. The pictures reflect 1)the location of the high idle cam, 2) the cam off the bike before modification done, I took the cam off and held a fitted washer of the same size over it and marked the cam with a magic marker so that I know where the low idle mark is at any point. I also marked the high idle point before removing the cam (right upper corner of cam). 3) the cam after modified. I ground the cam off at different increments until i got the cold idle rpm I wanted making sure I didn't violate the black marked area. As long as you do it slowly you can't mess it up, and if you do, I can't imagine that cam would cost more than $1.00.
Hope this helps someone.
