Look at www.fourstroketech.com and see what stroker/big bore kits they carry for your 300ex.

Also White Brothers has a 8HP Power Up Kit, check that out also.

There is a special kit for a 250x, its a typo its says for a 250ex, but they meant 250x (87-92)..... http://www.whitebrothers.com/ATVSections.html

go there and click ATV Engine, it should be on the first page.

Banshees around here are the same price as regular 400s, unless you want a LE shee.
