V-Star 1100 high idle after warm up

More than likely the carbs are plugged up(makes the no idle, popping from the intake or pipe and sometimes hard starting), and/or a vacuum line(s) Is loose/broken, and the carbs are probably out of sync (makes the high sticking idle/little to no idle). I have many article written about cleaning the carbs and fuel system. Get the carbs and fuel system cleaned out if you are not familiar with the process.

2004 V Star 1100 Custom, It has been sitting for several months, Bike starts and runs, It just Idles out of control when it is warmed up. ??? Any Sugestions ??

sounds like a carb problem(running lean/not getting enough fuel) and or your valve clearances need attention.

The idle is set too high. Check on the left side of the engine, about mid point of the jugs "V", you should see a knob near the middle. Turn it R/L until the idle lowers. (slowly!) (only AFTER it has warmed up.

take a can of carb cleaner an spray all around the carbs an intakes while it is running if it revs up or chokes down you have a intake leak try to tighten them up and see if that corrects it it could also be dirty air breater it would cause it to idle poorly until it warms up

You might have a bad voltage regulator that killed the battery,how long did it run? Was it on a high idle(choked)?
