Title: Twin Carbs
Post by: bikerboy on 18.12. 2012 04:29
Has anybody got any experience of running twin carbs on an A10 ?

Unable to resist I have obtained a twin carb 70mm alloy cylinder head. I aim to stick a couple of 930 concentrics on it and wonder if anybody has any advice on the jetting ?

Super Rocket barrels and pistons with a 357 Spitfire cam.

Any advice would be greatly welcomed

Thanks in advance

G'day bikerboy.
                    Just from memory 30 pilot, #3 slide, 106 needle jet, 210 main. Mine had no filters just velocity tubes and straight through pipes with reverse cone megas. Will check records later. I use two 30mm Kehin flat slides now.
Cheers

 Just checked, I get 50/100 for memory. The jets were right but the carbs were 932's. Should be a good starting point for yours though.
Cheers
