[QUOTE=peter650;19517731]Gday Twin shocker he wants to ride his bike on the road. It is not the cooling system, thats going to be a problem. You can jet a 2 stroke MX motor to run on the street, & it will not over heat on the open road. If you have a exhaust port bridge, drill 2 holes in the piston. Most old MX 2 strokes will surge on the street, but you can fix that with jetting. Just look at all the old 2 stroke GP bikes. Cheers Peter[/QUOTE

Riding on the road and beach racing are pretty much the same thing...........heat is what kills a 2T motor, and the reason for bigger jets is to provide a richer mixture which in most cases will lower temperatures enough to prevent seizing. If you take it easy though, the stock cooling system will be able to cope no problem..........but not WOT with stock size jets.
