[QUOTE="milk, post: 3991, member: 25"] ok guys here the situ... i've been battling a problem with my idle since i've got this bike end of last season. it's cost me some top spots in races due to getting into tight sections and the idle dropping way too low and stalling then being hard to start as is the nature of the manual decomp beast(that's gonna be solved shortly with a 450 cam but that's another thread all together) anyway i adjusted my idle finally and it seems to be set great, problem is now when i crack the throttle after the bike is warmed up on the stand with the choke off and everything the idle will hang for sometimes up to 30 seconds before it levels back out to a nice solid steady idle. i've cleaned my carb and jets, lubed and cleaned the throttle and return cable and everything. also my fuel screw does absolutely nothing. i can screw it all the way in and no difference, all the way out and nothing... should i go up one on the pilot jet?
