Will not run without choke

Idle jets are pluged up take off carbs and clean jets there are two jets in each carb put back together put some sea foam in gas tank It is a cleaner Get it at auto parts store Good luck MOPAR KENNY

The choke adds more fuel, so you might have a fuel issue. If it won't idle, but you can rev it up and it runs okay then, you need to have the pilot jets cleaned up. (I would go through the entire carb)

The pilot jet controls the air/gas fuel mix at idle . If the jet gets plugged up not enough gas gets to the emgine at idle. You will need to remove the carbs and float bowls and clean them, paying special attention to the pilot valve. Count the number of turns to remove the pilot screw and replace the same number of turns then turn counter clockwise 1/2 turn.

A “very helpful” rating for this answer? Thanks!

sounds like you have trash in your carbs u need to take bottoms off and run a piece of a wire wheel through the jets

had a similiar prob with a triumph. It backfired at low revs, a delay between throttle opening and revs increasing and bike felt like it wanted to stall at low speeed. Got the Carbs cleaned to find out the problem was infact Failing Ignition coil. Get those checked first before commiting to replacing other parts.

I am having a similiar problem. bmw r 1100 s will only start with full choke and will die if I cut off choke or give it any throttle. This is my first bike and it has been sitting in a garage for 2 years. I took out the carbs, cleaned them and rebuilt them. I didn't find any residual in the carbs and they were very clean. Today, I was able to get the bike running and took it down the neighborhood but after the bike warms up it idles at 6K! Man... If I can't find any answers from this forum, I will probably drop it off at the motorcycle shop just down the hill from me. Any suggestions anyone? I think I will try to drain the fuel and give it new gas. But still....
