its not a dig... i'm strugglin' obviously used the web link but im trying to order the topend 300cc kits and see they do an uprated wiseco piston kit.
now i have dave booths old 2002 fortuna.... will the wiseco's fit are they worth the extra ? and can i buy em in a kit with gaskets small ends gudgeon pins and exhaust gaskets ect ?
any help welcome...

The weisco pistons are not available to fit the 250 they only do them for the 300cc kit please feel free to call me on 01616136600 if you need more info

hmmm, not strictly true, indeed VHM do not list NSR250 pistons but to say they don't make any that fit? Well, that's another matter.

Maxim's Wiseco pistoned, VHM headed 300 revs like a 250 and makes better power than any other 300 I've seen, 10%+ up on what yours makes. How much of that is Wisco, how much is VHM, how much is difference between dyno's and how much is Mr.Matt's porting is another matter.

The stock 300 kit pistons are heavy ol' slugs, the Wiseco's have got to help both power and crank life to a degree but lighter engine parts tend to mean the engine can be tuned more rather than give a big improvement on their own.
This seems to be as near as you'll get to the kit you're after.
