2006 Rough idle after warm up and sometimes cuts off.

Hello, My 2006 runs great when I first get on and ride for 20 min or so. Then I noticed at a light that the idle was becoming eradict. I had to give it lots of gas and release the clutch slowly to get out of the way. When I get up to speed things seem to smooth out but its when I am stopped when things start to go wrong. Its shut off on me at lights more than once. NOT GOOD. Any ideas?

Do you have a check engine light?

Sounds like one of your sensors is bad. Could be MAP, TPS, or O2. Best to check the codes.

No check engine light. I just let it warm up again and it sounds good until it gets warm. At 6 bars the fan cuts on but after about 5 fan cycles the engine starts to miss. Like its running on 2 cylinders or something. It corrects and then does it over again. When I give it gas it hesitates and then runs good (2000 rpm). When I release the throttle it idle eradically.

Is there another way to check the codes other than taking the bike to the dealer?

U can ck codes with a tuneboy...when was the last time you changed plugs? Synced throttle bodies? Do you have a "whoosh" sound when you open the gas cap?

Tune Boy.. Well I guess its time I got one of those. My bikes got 14k miles on her and I haven't changed the plugs yet. So far I've taken off the cover for the airbox but I don't have a clue on what to do next. I see the hoses that need to be taken off and the two screws in the back but it still doesn't budge. I'm not liking what I'm seeing as I look down the intake though.. Lots of black crud caked up around my valves. Is this normal? Can you tell me how to remove the airbox?

I know this is old news for some of you. I found an old post about how to remove the airbox to get to the spark plugs.. And yeah, its easier than it looks. I had to use an air-compressor to blow out the built up water on top of the plugs it looks like its been like that for a while, rusty and all. The plugs look burnt but what bothers me is that I don't see shiney metal when I look through the little spark plug opening I see built up crud in my cylinder. I've got an aftermarket low-boy exhaust with the 3-in-1 tune. Does this mean that I'm running way too rich?

Thanks Bohdan, now I can clean it out before I put everything back together. Now I'm thinking of putting in the same old spark plugs while I clean it out (the first go around anyway) before I put in the new NGK Iridium spark plugs.

Why not just go ahead and throw in fresh plugs?
