Keep an eye on mounting bolts and exhaust bolts for the first few rides, after you check them a few times they usually take a set and stay tight. Be sure to use a second exhaust mount to hold the muffler from shaking around too.an it would deff help if i could lower the engine its a hella tight fit but **** if it aint broke dont fix it so that s o b staying where it is...also the bolts from my engine stud almost rattled out after the first ride... maybe two mins so used some blue threadlocker loctite
