well 400ex18 i wouldnt worry about it being to loud because the limit for this weekend is 106 and the highest jeff@quadshop has gotten is 107. and they are testing it at 2000rpm from a yard away so i bet youll be ok. my friend races dirt track up there and he has a crf450 dirt bike with a curtis sparks on it and it passed. that is if your even talking about jolly roger
