stock cfm is around 305. I would say stay with the stock Nikki if yours is in decent shape and you're not going to be going wild with porting etc. They're a really good carburetor, biggest problem is wear and tear, as they are getting pretty old and most have a lot of miles of use on them. As with most carburetors wear around the throttle shafts is one of the biggest killers as it is hard to fix. Seals and such are easy enough with a rebuild kit. Jetting and full throttle fuel enrichment are quite a bit different for the rotary, so any old off the shelf carburetor won't work very well without a fair amount of modifications.
