I've done some research here and am still unsure about whether or not there is a different size jet for the stock basic nt carb compared to the nt speed carb. Has somebody measured? I don't have the tools to measure myself.

thanks,

Thanks for posting that link, Agreen. I can see the throat is bigger on the speed carb if I look at them side by side. I was hoping the stock carb had a smaller jet.

I suppose I should just bust open my wallet and get my yz80 expansion chamber put on. If I do that, with any luck I might get away without having to change jets.
