I got my new bike also and i am very impressed with this bike. It is a 2005 650 with 6k miles. This thing feels like a feather compared to my 95 triple and seems twice as fast. It has a leo vince sbk exhaust on it which sounds awesome. It was laid over and has a little cosmetic damage under where the oil filter is, other than that it is in great condition. The inspection ran out and the front brakes look a little worn, hopefully i wouln't find any other surprises when i take it to get inspected. I'd like to also say i got a pretty good deal on it. Paid about $4350. I just wish it was warmer out now so i could enjoy riding it more. I have a few questions about what type of oil to run in this. Would it be a good decision to run full synthetic oil in this or semi-synthetic? Also, if i replace the air filter with a k&n will the engine run lean? And will i need a powercommander to tune it?
