dont do it!!!!!!!!!!!!!! wait till riding season is over then build you a "room" from some big tarps, put the engine into that "room" with a couple of space heaters and maybe even a heatlamp poting at the motor, wait a couple of hours turn the heaters and lap off! then paint, wait till fumes dissipate then turn the heaters and lamp back on. thats how i painted my 750's frame, tank and side covers in january.
