Having run all sorts of different configurations over the past couple of years, this is the best I've had. Carb came with a bgm needle marked "28" which proved a bit rich. I tried a JJK thinking this would be leaner over half throttle only to find the opposite. Fitted a GJH and it transformed the midrange but needed the main lifting from 115 to 128.

22mm Jetex
130 main
50 pilot
Remote filter
16/46 sprocks with Li 150 box.
Running in at mo so running pretty rich, ran like a bag with a 123 in, may lower to a 128 when run in,I think personally that with Jetex carbs you never get two the same,I also used a shorter float needle out of another jetex carb to let more juice into the bowl....So far so good...everyhing crossed
