It seems every time I start my bike it's a different animal. Fueling seems to be constantly off. I'm not sure if I have a sensor going bad, a bad fuel injector, fouled plug, or something in the throttle body that's busted but I'm at the end of my rope. Clutch out idle afr is 13ish clutch in bike wants to stall. I was heading back to work and I was holding it at 4k and the afr was at 13 then it dropped to 10 or so. Rolled throttle afr came up rolled off dropped etc. Are there any good aftermarket stock size injectors out there?
