They were the first "good" carbs made back in the day, they set the bar for all designed today, and their still probobly the best carb out their..... But they are spendy!!
hmmmmm...sounds like a nice addition......im soon to be running race fuel......oh boy!!!....would my ride benefit more from from one of these carbs????
the whole thing is changing a needle.. there are NO jets..they look pretty good from what i was readin on the site, and sounded like they jet it for your particular application to get ya close, then it sounds like just changing needles to fine tune???
