Hopefully I will find some help here. My 1988 VMax doesn't want to idle smooth after motor reaches operating temp. Here's what I have/have done. I bought the bike 2 years ago with Supertrapps installed. I put a K&N filter and thus had to do a stage 1 kit. I cleaned and sync'd the carbs at the same time at my brother's bike shop. I did a new battery and coolant flush yesterday. Stator tests fine. Reg/rectifier is new. No air leaks at boots or around intake. I did the "crimp fix" as noted on Outlaw VMax's page to improve charging. I have spark at all four cylinders and plugs look good. Bike runs fine, all the power I want, just after reaching temp and stopping at a light, the idle wants to be erratic and dip a little, up and down. I have noticed my fuel pump's "ticking" to be getting louder/longer lately when I first turn the key to "on" after sitting for a length of time and am wondering if this might be a fuel pump issue, although most fuel pump issues are at speed rather than idle and my bike rides at speed smoothly. I haven't done a fuel output test yet as I haven't been able to find a fuel quantity amount for the test in the manual. Anybody else had a similar issue? Any help is greatly appreciated.
