What do you all fell is the best carb size for a 330 topend kit??? I will be riding mainly Trails and an occasional sand pit but mostly Trails. Who do you feel makes the Best carb?? Take in mind It will be mostly Trail Riding with a lil MX every now and then.

If you're doing a little MX every now and then, you'll need good throttle response. I'd probably recommend a 38mm Air Stryker.

If you were running a smaller bore, like a 265, I'd probably recommend a 36mm, but on a big-bore 330, you'd be restricting your power in the upper RPMs.

A 39mm will give you good top-end horsepower, but you'll be losing throttle response. If you were just running dunes and not racing, I'd suggest the 39mm. But since you say you are doing a little MX, I'd suggest a 38mm for better throttle response.

I run this same carb on my CT330R and like it alot. I have heard of people going with the 39mm for more top end! I think the 38mm suits the R the best for woods riding...just my .02!

38mm A/S is definitely the ticket~!
