Those have been around a long time, I'm thinking there were originally used for on road racers, when ppl started usin them on off road, they were getting them so out of tune, NR and other engine companies were better off using the 2 needle carbs, rather hearing complaints from all the customers that would mess them up so bad, then bitch at the companies for bad carbs.
