03 R6 Cutting out?????
I have a 2003 Yamaha R6 (fuel inj.) with about 11k miles. I have been trying to ride when the weather is warm (50-50) but it finally got nice the other day (70's). When I was in the middle of no where on a nice curvy road I noticed that the bike would stumble or miss on 1 or 2 cylinders at low rpms. So i figured a good run with the shift light on a couple of times would help. Even worse!!! Cuts out on 1-2 Cyl above about 10-12k. And when the bike would idle it would only hit on 2.
So Last weekend i replaced the spark plugs. All looked good, just slightly burnt electrodes. It seemed to help but when the bike gets warm, like 180 water temp, it will start to miss at idle and will still cut out at high rpms?
Any Ideas on what it might be or what to check? I thought maybe injector? but at $90 a pop that wouldn't be cheap. Thanks for any help!
