[QUOTE="_JOE_, post: 1335358, member: 77507"] I think a 450 is crazy for 75% of the people out there. They will go longer on engine parts, but can and do break as well. I would get hurt with one. There hasn't been alot of changes to 250f over the years. Pretty much the same engine with updated porting, cams, valve springs and some cylinder changes. The statement you made about "buying a bike this weekend" might not be the best idea. Don't jump into something because you have money burning a hole in your pocket. Hold out for a really clean low hour bike if you plan to keep it long and ride it alot. The leak-down test will check the combustion chamber seal by pressurizing it and watching the pressure drop. It can be very useful in diagnosing burnt valve seats, leaking rings, or any other condition effecting the ability to seal the combustion chamber. If there is leakage you can actually pinpoint it to intake or exhaust valves or ring seal by simply listening to where the air is escaping. [/QUOTE]
