cheers guys, I've beein looking round ebay seen some good prices for the 8 port on there and also other motors like the Rossi Mamber. just want a good priced 21 to have some fun with this year when the weather starts getting better, i wa running my hyper up a moutain in the snow today was good fun till i ran out of fuel [:'(]
My mach 28 prob doesnt have any low down torque, its got little compression so a new engine will feel completely different.
what pipe do you recomend running it with.

sorry one more thing how much better would the OS V-spec be seen a few brand new ones on ebay. the only thing that woukd put me off is the front bearing I keep hearing about.
