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.

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? :confused:

ChattyS3, I thinks thats all I'm going to do. I'm also ordering the new rubber sealers (that fit on top of the coils) to prevent moisture from getting into the spark plug wells. I think my problem starts when the water that I found in the wells gets so hot it boils since things get bad after things warm up. But who knows. I'll probably add some fuel additive every now and then to keep things from getting worse but I don't want to cause problems by spraying something into the cylinders to loosen up any carbon build up and risk something getting stuck in my valves. But yeah, I've already ordered the new plugs.

Blastap, I'm also removing my SAI so I've got to take the bike up to the dealer to get a new download so at this point I don't think I need the scan tool.

Why didn't I do all this over the winter !?!

Update:
Since my last entry I've installed new plugs, coil sealers, and bypassed the SAI with British customs kit. I've taken the bike to the dealer and download a new arrow 3-1 map with no SAI and had the throttle bodies re-synced. The bike runs much better, smoother, responsive.
