i have a very nice 4 mil banshee with brand new top end. 4 mil crank, reed spacers, stock swing arm installed, +4 swing arm included, full fmf exhaust. want a nice yfz 450 or trx 450r. have pics to send. 816-273-7450
i traded a blaster for a banshee that the top end blown up. had the same problem. one piston was severly messed up. the cylinder has a nasty knick in it. it was stock bore, and had to bore it out to .40 over. i didn't have any problems with the crank but it is a good idea like the others have said to get it inspected or even trued and welded. i went through a local shop here for top end kit and with everything that i needed including gaskets and such was around 500. i am aware that i over paid. great time to get prot work done since the top end is apart. are you running a cool head?
just a +4 timing plate with coolhead. k&n pod filter. thats it. i wanted more top end so that is why i switched. i have read that fmf's give more power top end while pc's give more bottom end.
