2004 Vstar 1100 idles too fast when hot. It sat for a while and when I first started riding it consistantly I would have to keep partial choke on to maintain idle. Recently it started idling too fast when hot and seems to get too hot.

SOURCE: Vstar 650 classic. only will idle.

hello and welcome
this is a very very commom problem after the cycle has gone over a storage period of anything over a month or so. what has happened is the deteriorated fuel has plugged the idle jet, and possibley other jetting. this is verified by pulling out the choke allows it to run. because this makes of for the loss of fuel the jets are not produceing. so to fix this you will need to remove the carbs and take out the jets and clean them thoroughly with a carb cleaner and possibly a very small gauge wire to break up builup. especially in the pilot jet. unfortunately fuel added carb cleaners dont seem to work for this kind of problem and to fix right they should be disassembled and cleaned thoroughly. thank you.

Hi there!

Open up the carb and clean the jets with pressurized air. I also suspect water on the carburetor reservoir, before opening the carb, drain it first then run. Also, make sure the plugs are clean. Pull on the choke when twisting the accelerator, if it accelerates well, then warm the beast at normal temperature first before twisting the throttle hard again.

hope this helps-

The problem is that your idle is adjusted to low just like mine, you need to adjust your idle

Dawn it is running lean if it will run on 1/3 choke when you choke it like that it actually restricts the air flow into the carburetor my suggestion would be to remove the carburetor and clean it real good and try that first before going anywhere else

SOURCE: vstar 1100 yamaha will not idle, only runs with full choke

You will most likely find that your Air Cleaner element is blocked & possibly may have sucked up some leaves reducing air flow.
