From a guy who
owned one, and had less trouble with it, overall, than with his People 250, one thang I recommend you do right away: Put blue thread-locking compound on every bolt associated with the exhaust system,
except for the two that bolt onto the engine's exhaust port. And keep an eye on those, every so often, too (like at oil changes... just check that they're snug, and not backing out). Just take out the bolts one at a time, apply a smidge of the blue goo, and torque it back in place.
