I was donking around Pirate and I happened upon a post about moving gas tanks on Toys. Seems that someone had problems with the exhaust vapor locking (vapo rubbing, vader darthing) and whatnot the motor from exhaust heat. My mufflers are going to be running 2"-3" below my gas tank, should I be worried about that? The rest of the mufflers are open to air. Anywhooooooo Oh and if it is too hot, can I run some sort of heat shield? There's the muffler, they're snugged up to the frame, the tank iwll be sitting on 2" stock and some rubber strips.
