need help

new 09 krl did not ride from october to november when putting bike away bike will start cold on choke and run. if you let bike come up to operating temp than bike wont hold idle unless you manually throttle. if you let bike stall when engine warm will crank and crank to start. sometimes wont start .
when trying to start when this happens you must hold throttle wide open to start., after bike cools down you can restart on choke and ride ok with no proble until you shut it back off than issue rehappens:(:(

I would pick up a can of Sea Foam. Dump the entire can in the tank then fill the tank with new gas. Take the bike for a 15 mile ride:animal0019:. I will bet your problem goes away:11a:….

Hi valleyrider. Welcome to the forum. I hope you find everything you are looking for here.

Now that we have the social formalities out of the way, I'm sorry to move on to a sour note regarding bike ownership. Our current gasoline supply. It sucks. Gasoline with ethanol has additives in it to keep it from separating. From corroding. Ethanol sucks up moisture. An ethanol blend gasoline can begin going bad in a week. It can gum up your carburetor jets and passages. Today's fuels are geared towards fuel injected vehicles. We with carburetors are the dinosaurs of the roadway.

First off, I'd drain the float bowl. There is a screw down there on the very bottom you can back out and let the fuel drain out. Water traps in there, as does other contaminants.

If caught in the initial stages, there are some products on the market that might dissolve the buildup left by the old gasoline. Sea Foam enjoys a remarkable reputation. It will clean your carburetor and make your dog smarter. Don't give it to the dog. He gets smarter through osmosis. Chevron Techron Fuel System Cleaner has worked OK for me. Berryman Chemtool B12 works. You will need a much stronger dose than recommended on the product container. Most instructions are geared towards a maintenance program, not a "therapeutic dose". A full can to two gallons of gas might sound harsh, but there is nothing in the snake oil that will damage the carburetor or engine. Let it run for a bit, let it sit overnight, and try it again. I've seen miraculous recoveries in 72 hours.

EDIT: I note you put in BG44K. GOOD STUFF! Sounds like your Pilot jet is gunked up. It may or may not respond to snake oil treatments. Allow the chemicals to work.
