Carb Identification? Gold Top 48mm
Can anybody tell me what brand of carbs these are? They are 48mm bore I got them with my Ski. Hydrotoys says he thinks he got them from WFO or Fullboogie but he is not sure. I am going to sell them or trade them for a stock set and just want to be able to describe them properly.

Mikuni.....LOL.........no serious, the internals look like the Riva Bombsite carbs.

As far as I can tell it is a stock mikuni 44mm I-body modified to 48mm top removed and velocity stack pressed in and bombsight installed. I know there are several companies that do this RPM. BlackJack, etc. I just would like to find out who did this one so when I sell or trade it I can communicate this properly. I have someone who wants it already but it is still nice to know.

I was just trying to figure out what brand or who made them.
I think I will hang on to them for awhile I just need to figure out proper jetting for a stock setup it was running rich and loads up at idle it has 115 pilots 165 mains 2.3N&S and black spring. Mark said they were jetted for a tripple. The plugs were dark and I did foul a set in two days of riding.
I have 2002 with the following installed
VF-3's with stuffers
Jetworks mod with sound suppresion
48mm carbs on R&D intake
2" extension on a early pump 87 nozzle
stock ride plate
13/19 solas repitched to 14/20
max on glass was 59 gps
waiting to install
modified stock head 140 PSI
advent with D-70 curves
Gas Valves from Island
Sound suppresion bypass Tube?
I have coming a modded ride plate and stock sponsons to step I will have the tach installed and hope to see some gains I am going to try a loaner 6.5 nujet I will be upgrading to the HO and dynafly pump later
I am hoping to hit high 60's at least with handling upgrades and prop after that I will start with the head and advent and SS step by step.
