Bike runs rich and cant get to idle
SOURCE: motor bike wont rev above idle weth choke on
This to me sounds like you need a carb cleaning. If you have let the bike sit for an extended time the carberators maybe clogged or gummed up. This has to do with the new gas that is out there now. It is cheap and with the introduction of Ethanol alcohol now it is even worse on being stable for long periods of time. I have seen fuel go bad in as little as 3 weeks.. One quick check you can do is open you fuel tank and smell the fuel. IF it smells like varnish it is probably bad. You can drain the tank and add new fuel and that should solve your problem. Keep in mind, that the carbs need to be drained as well to get the old fuel out of there also. Make sure you have a battery charger going when you start crankin that puppy, because you will need lots of extra juice to get that baby to fire up. If it is starting now and runs on choke, that means your idle jets are clogged. Best repair is to remove carbs and clean idle jet. Unless it is fuel injected.
Let me know how that goes and we can proceed from this point. I am a certified mechanic from MMI as well as a HDTV GURU. Smiles. have a good one.

Hi mikelapt
You will have a carby problem. When the choke is one, and different fuel circuit is used. When you turn off the choke, you go back to the idle circuit of the carb is used, when under throttle, main jets kick in. You probably have a blockage in one of these circuits. Strip the carb down, clean with carby cleaner, blow out all air circuits and jets with compressed air, then setup the idle mixture and tick over speed. Always work with fresh fuel, and drain off, discard any fuel older than a couple of months. It goes off, and turns to a gel like substance that blocks up your carby. Hope this has explained your problem. Happy to talk to you more about it. A FixYa vote is a great reward for for my time taken to explain this to you. Cheers

Your low speed jet is pluged. You will have to remove the carb then remove the screw in the float bowl. You will see a main jet and a pilot jet. You will have to remove the brass plug that covers the air ajust screw. Then turn it in to find out how many turn till it bottom out. Then remove the screw and take carb cleaner and blow out all passages.Then reinstall all jets. Hope this helps.

Sounds a lot like fouled fuel jets in your carb; you may have a little work to do.
If the jets do not allow sufficient fuel to pass, using the choke can 'cheat' the carburetor by restricting the flow of air and restoring the fuel-air ratio.
You can't ignore this problem since the 'cheated' condition does not let the engine develop the power for which it was designed.

this prob happens allways in carburated engines that the car or motorcycle is running lean or rich . because the air - fuel mixture ratio is not right . so you should open the carburator and remove the air filter you will find two screws in the lower front section of your caeburator. you can adjust them by a screw driver until your car is smooth
