[QUOTE="harper, post: 1296694, member: 88451"] My throttle wouldn't return quickly even with the Throttlemeister removed from my handlebar. It took several seconds for the engine to drop back to the lowest rpm but even that was above idle speed. The throttle had to be forced closed to return to idle. This is a bit of a dangerous condition that I had ridden with for some time. So, I went to see audiowize to have him save my bacon again. The cable tie-wrap technique proposed by Kurt2004FJR below is what audiowize and I used to rewind a turn onto my throttle return spring. A previous owner had probably unwrapped one or two turns sometime earlier. With the throttle fully closed the hook on the end of the spring didn't touch the boss it was supposed to engage. We used about a 1/8" wide cable tie with the end cut off and drilled a hole of order 0.07" diameter close the the cut off end. Wrapping the cable tie tightly a couple of turns around a finger introduced a curve that took a set for long enough to feed the cable tie under and around the throttle shaft and spring assembly. That took some fiddling as did engaging the hook in the hole and releasing the hook from the cable tie. Having someone position the throttle while fiddling with needle nosed pliers to engage or disengage the hook on the end of the spring was helpful. [/QUOTE]
