Well if it is poked and stroked the major work is done. Really sounds like a fast 300. You could do a cam with a port and polish. I would probably play around with the sprockets and tire size to get the right combo. I would also focus on the suspension.

Reeds? I have 20" and 22" rears I change around. Taller tires = more speed, smaller tires = less speed and more off the line. I lke my 20" but if ya ride rocky trails you will want a good swing arm skid plate. Suspension will make a good quad. For the front there are dimond j relocator brackets on ebay. It will let you run 400ex or 450r front shocks, much better then stock 300ex. On the rear you can swap out stock for a 01 (only 01) raptor 660 rear shock. However the raptor shock will have to have the rez hose made longer to find a good spot on the frame to mount it 16" hose. Or you could use a banshee rear shock but the air box will have to a little reshaped.

If that guy raced on stock suspension then I think I would take what he said about the internals with a grain of salt. any way I agree with jgar those mods should atleast get you riding smoother.
