Hey, I have a 2008 WR450F Supermoto, i've had it for a year now. when i bought it, the guy told me the stator mod was done to the bike. It has a street legal kit with high/low beam, horn, signals,etc. The battery wont charge much while riding and i have to use the kick start in order to start it. ( the E start will work for a short period of time after i have ridden it) My problem is when i am riding with the headlight off and than switch it on, i feel the bike sputter. So i assume the bike is loosing power some how. What do I do to resolve this?
