So, I came from many years of being a Doo rider and I always pulled the foam out from the engine bay for a couple reasons.. A. is when they got wet in past years on a Doo it added weight. B. I don't care about the noise reduction I like to hear what's going on down there anyway. C. I seemed to make the engine and clutches run cooler. Anyone see any reason on a N/A or boost to keep foam in?
