XB rough idle

[NZBuell]

Hi guys, my 2010 XB12Ss is running really bad at initial start up at idle. Runs ok and idles fine when warm but diagnostics say it runs lean, cough and splutters and keeps getting leaner till it cuts out. Any ideas out there?

Is it throwing any codes?

Have you checked the intake seals? If their original, then they're only about 7-8 years old.

To help diagnose your problem, Give us a little more info,

1. How many miles on bike?
2. Has it ever set for a very long time?
3. Have you ever run fuel injector cleaner through the system?
4. Have you done anything to your bike recently?

Silverrider, bike has supposedly only done 5k miles, so would have done a lot of sitting and yes I ran some UCL/injector cleaner through it. Have it at a tuner at present (who has put it aside for a while due to other commitments) and he has it running great at normal road speed but having trouble at idle.

Hey Lunatic, I had the IAC replaced. Thanks again for your info.

34nineteen, I replaced the seals, the engine light came on briefly once but went out after a couple minutes. Didnt scan it to see what the code was tho.
