ive heard good things about ported 330's and 370's by ESR. that backed with a nice swing arm, paddles, suspension and a rider with the balls to lay on the throttle even when the front end wants to kiss your helmet, you should have a good platform.
310 would run good but i doubt would run with "highly" modified shees.

I have a 85 250R ATC it has the stock cyl on its 3rd bore completly ported.
It has a 38mm Mikuni and a K@N with Vforce reeds and a Answer roost boost that I disconnect when racing.
The trike has out ran every stock 4stroke that I have raced and alot of Banshees but there is always a few at the dunes that are running some major HP that can beat me in 300ft.
I was wondering if a Coolhead is worth the money.
Or if I just need to invest in a 310kit or bigger to beat those highly modified Banshees.
Any ideas?

Before you go spending the big bucks,
you should try different size sprockets,
it would be way cheaper. Along with bigger back tires
