I am looking information as well but on a 300 explorer. I have good ATV but would like to convert to 4 stroke of around 400cc. Do you have any info.

that's asking alot, you may be better off finding a donor vehicle. you'll need the radiator, wiring exhaust and clutch covers just to start

I have heard of people doing this swap but I don't know why you would want to I like my 2 stroke sportsman so much better then my 4 stroke sportsman. Both my quads are 400s but the 2 stroke has alot more snap to it.

Ride it like you stole it!
94 sportsman 400 SOLD
01 sportsman 400
