it's either fuel, spark or air.... I'd start with stripping the bike down, check the filter/clean the filter, inspect the throttle bodies and replace the plugs. Someone already mentioned contaminated fuel so since the tank will be off anyway, drain the old stuff out and put new fuel in. There also should be a way to pull a code through the FI light but I'm not sure how to do it, you may want to research that. If you don't already know, there's a free manual in the file vault that you can download, should be a lot of help if you need it.

well the fuel is good, it's been happening over 3 tank loads of fuel, the bikes being service this friday, so fingers crossed, i think that this could be linked - the battery keeps going flat!!! i've checked the batter it's only 5 months old, the charge voltage is at 13.5 to 14.5, someone told me it could be the alternator or retifier causing the problem but i havent got a clue still, but many thanks for the sugestions so far

I would start the bike, rev it up a bit while it's sitting there and put a multi-meter on the battery. With the bike not running the meter should read a little over 12 volts, running with the throttle open a little should put it around 14 volts. If it's running and under 12 then the alternator...(actually I think it would be a stator on a bike) isn't doing what it's supposed to, low voltage could cause an ignition problem, especially when the bike calls for lots of spark in higher rpm's. Does the F.I. light stay on or is it intermittent?

No fi light at all, checked the charge rate and its fine, even put a new battery in , no difference at all, been thought the manual, a mechanic friend said it won't be spark plug or coil cap , because the bike would misfire!

Ok, if I'm thinking right, at 10,000 rpm's or so the secondary fuel injectors are supposed to kick in or the timing of the bike changes and changes the fuel curve through the computer. I know that the power commander plugs directly into the fuel injectors so I'd lift the tank and check all four of the power commander/fuel injector plugs. It's a long shot but there may be an issue there.

I'm having the same problem my bike will warm up and drives perfectly fine except when it's in gear it won't rev past ten grand but when its in neutral it will hit the red line no problem and I can't figure it out haha I replaced the ecu cause I thought maybe the undertail exhaust fried it but I was wrong still the same problem

Well, your mechanic friend isn't completely right. This most certainly can be caused by a bad or failing coil without necessarily hearing a misfire. Check them with a multimeter per the instructions in your service manual.

did u solve your problem

I have an issue much like yours and I thought I had it figured out. I changed my intake air temp sensor and it ran normally for about 6 days. Then the same problem came back. Even wth a new intake air temp sensor no help. The one I used to replace the 1st one came from a smashed but running bike

Well, since this thread was 7 years old when it was re-opened in February and since the OP hasn't posted on the forum since 2009, it's unlikely your going to get any help from him. You might be better off just starting your own thread with your information in it so there isn't a lot of confusion about what has happened to you.
