My son also won a champion ship in 97 on his 95 one. Don't know if you have rode the earlier model, but they are so different to the later ones, so much harsher and rougher, no balance shaft like the 95 on model, more cruder suspension and of course no cassette gearbox. I have been lucky to have amassed a lot of new spares over the years, ie crank, barrel, head, pistons, rings and gaskets, a few RS250 NF5 bits, ie pistons kits and cyl head O rings fit the NF4. Good luck with the rebuilds, and keep us posted on progtess.
