My neighbor has a 2000 can am ds650 for sale 2400 has a yoshi exhaust,k&n filter,and a jet kit.now he claims these things do 105mph and will rape a banshee or even a raptor.is any of this true I've rode my buddies 660R with about the same mods and its scarry fast.but I've never rode these bombardiers. I was telling him I'm looking for a banshee when he told me he just got this thing and made all these claims.but if its all true are these things worth 2400 what about maintenance on these are they expensive and a pita to work on?it looks brand new no scratches on the plastics everything looks brand new.so whatcha guys think good buy?
