Ok I am not a fan of burnouts and have only done one or two ever. My question is: is doing a burnout bad for the bike in any way? I am about to go grab a new set of tires and it just seems a shame to throw out my existing ones with so much rubber left on them. But I dont wanna decrease the life of my engine by doing this. So if I burn off whats left of my tires do I risk damaging my bike?
