Thanks for the replies. I have the carbs done and ready to install once my cylinder heads are finished. I split the difference between the Bing book and what was in the carbs by starting with a 2.68 needle jet but leaving the needle in the 2nd notch. I know this may not be the final jetting but since I am completely reassembling everything with many parts new to the bike I want everything as close to good as possible.
I stated in the original post twice that I was using R100RS parts, not the R80 parts.
