anyone have an fmf megamax on their 250ex? my friend has one on his 400ex and it sounds really nice but as far as looks goes its an ugly pipe. what about a white bros slip on..i dont have much money to spend on a full pipe right now so any help would be useful. another question.. does anyone know how to tighten the swingarm on a 250ex cuz i have like an inch of play on each side and whenever im on the road it sways back and forth like a mofo.
