It took me quite a while to get it in the right place. I have had the cowl on with the mounts in place, but with the engine now mounted, I won't be able to tell if it changes anything. It shouldn't, but it is my next step. First, I will be measuring the distance from the exhaust port to the cowl inside wall. I am trying to determine if the j-tec wrap around pitts muffler will fit. If the distance is too small, I will see if they can custom build one with a narrower exhaust box on the side. I don't mind spending the bucks if I an get one to fit.
