Worked for me!
I had RB Designs do the divider plate mod. to my carb along with all the other stuff(bore size increase,slide work, fuel curcuit rework, different jets/needle, etc.,etc.) that Ron does and it was a good mod. I have a 240 motor with a Gnarly torque pipe and PC S/A. Ron literally did a one day turn-around for me as I was heading North to ride with Motochick and ATK Adam for a extended weekend. I sent it to him overnite on Monday evening, he got it on Tuesday and did all his work to my carb and sent it out Wednesday morning. I got it on Thursday morning, installed it on my bike (which was already loaded on my trailer out in the parking lot ready to head North) that afternoon. I just started it on the trailer to check for leaks and make sure it ran and then left for my weekend adventure. I had chatted with Ron quite a bit to tell him everything I could about my engine/mods. and he installed the jetting that he felt was appropriate for my situation. I ended up riding 116 miles on Friday and 100 miles on Saturday and just plonked around on Sunday at a trials meet that Motochick and her hubbie ATK Adam were participating in. I DID NOT change any of the jets/needle/needle position that Ron had set the carb up with and it ran great! A definite improvement on low end response/low speed tractability and crispness thru-out the powerband.
The craftsmanship/machine work was superb on the carb, I'm used to doing my own machinist work so am pretty AR(anal retentive for the masses) when I have to have someone do work for me. The bore size increase transistion was so smooth and the brass plate install was fantastic!! Anyway I was pleased to have something work out this well from all aspects so decided to invest my time sharing my experience by responding to this post. Ron's phone # was listed on a previous post so call him up and he will work with you! Enjoy!! CD
