AZRickD's RB-Design Carb Mod Report

[AZRickD]

Last summer I had Ron do a squish band mod. Major, major improvement.

This spring I decided to have him do a carb mod. I was most concerned with what it would do to my carb jetting performance at altitude. Phoenix-area riding is 2,000+ feet and 95F at sun-up this time of year. Flagstaff is 7K to 9K feet at 80-90F in the afternoon.

Last year I would have to lean out my MJ to 162 to cure the bike not wanting to reach the upper revs in Flagstaff. The PJ was around 38. This year in Flagstaff (last couple of weekends), I have had the MJ at 168 and the pilot at 40. It has been working very well. Just a touch of hiccup when I'm reaching the upper elevations that our riding in Flagstaff has to offer. The pilot might be just a touch rich.

I washed the bike and warmed it up tonight with a tour of the neighborhood lofting the wheel over imaginary obstacles. It ripped. I may have to do a plug chop to see if I can run similar jetting down here (and/or just adjust the needle clip).

What have others experienced with the RB carb mod in this regard?
