Forthcoming BSSO production racing class is to feature exclusively this combination with Franspeed race pipe. Has anyone got experience of this carb / kit combo to offer a ball park starting point for the jetting?

I will check in the morning as I can't remember
Thinking 168 main
55 pilot(maybe smaller though)
1.5 down on clip
Dq266 atomiser
300 float valve
Strobed to 17 degrees
Runs pretty nice around town
Great on the motorway
Ps this has a franspeed road pipe though so could be worthless info

AS the BSSO production class has now done a couple of seasons with the RB20, Franspeed race & VHSH30 combination what's the general consensus for optimum jetting?
I've used my RB20 for sprinting but feel the VHSH might offer a bit more top end than the PHBH currently fitted.
