Cool Re: Airflow-constricting flange inside my carb...

The new NTS 66 carb boasts a millimeter (I think) wider flange, all the way around the ring- I'm wondering if anyone is shipping it stock with the kit yet- just a matter of time I guess.

but you are absolutely right- I think too that this is the real limiter to mixture flow- it wouldn't make sense to dremel the ports on the motor and leave the carb the same-

On the other hand, the billet intake from Pirates and Creative Engineering puts the carb right up next to the motor, and really improves performance for less than $15.

I reamed the billet intake out further, the alloy goes quickly.

the danger with over-reaming a stock carb is to create an air leak I guess.

I like the bilet intake and new NTS carb- (although I still have the stock on for now)- It's the cheaper fix than the CNS racing carb- the jet is bigger too they say-and there's less clearance issues in the frame- it's shorter-

but still a bit tricky because you have to lower the cable guide by cutting a bit off-
