Hi I have had my bike from now since summer 2014. Installed many mods, and covered 6500 miles. however in the last six months i have noticed when slowing down with completely closed throttle, as the revs drop past 6k down to about 4k i have engine warning light on display, the bike runs perfectly, making good power and is as smooth as the day i got it. Amongst my mods are an aftermarket exhaust. I suspect a tune is needed, and have booked it in for a power-commander and stage 2 DNA air filter/air box mod. If it is leaning off that should correct it on the dyno. but having spoken to the guys at the shop they suspect it could be a sensor playing up. (throttle position) Has anyone had anything like this before? I will be carrying out the work anyway as I have wanted to do it for the last two years!!
