Idle problems I have a yamaha 650 V-Star Custom. I am having trouble setting my idle above 1000rpms. The bike cuts off. The only thing I can do to keep it from cutting off is to keep the choke lever pulled out about 1/4 of the way. I have turned the idle know to the right as far as I could. I have changed my spark plugs, my oil, oil filter and air filter. With no sucess. Any ideas besides taking my carborators off?

    Had my 2005 V-Star 650 Classic sit outside over the winter under a cover. Had problems starting and added some dry gas and conditioner. Bike started but push choke 1/2 way in and it stalls due to low idle. Any suggestions before I have to bring it in the shop?

If the bike has been sitting over the winter or a few monts , the carburator is probably varnished up. Need to take it to a shop and get it cleaned and tuned. I usually take my carb off my dirt bike after it sits all winter and clean all the needle valves and then tune it. Good luck

You should have a idle adjustment knob under the gas tank, left side.

Hmmm... this doesn't sound like a problem that belongs here... By "cuts off" do you mean stop running, or misfire? Carb. problems often are the result of the bike having set for many months or a year or two with old gas, which can result in a varnishing like of the fuel in the carburetors, which can clogg small passage ways, and subsequent no-idle, or other poor fuel delivery. Problems such as this require repair by knowledgeable mechanics. Other things which can upset correct fuel/air mixture are modifications such different exhaust system, air cleaner change, camshaft- any mod of these can require some retuning.

Bike backfires and at an idle it shoots out a blue flame

Purchase a EFI controller. I suggest a Fi2000R. It is easy to hook up and fairly easy to set by the instructions.

the best way to do this is buy the aftermarket exhaust and keep the baffles in the exhaust and run it for 50 or so mile then pull out one of the plugs and if its gray you are fine if its white or black you will have to rejet
