Carb Set-up for 200 Stage 4

[vespinello]

Asking about GP SIL 200 Stage 4 carb setup

The engine 'll be fitted stock without any modification + Exhaust Clubman AF 42 mm
Use : touring!
Wich carb do you advise ?(I won't to use a Spaco/Jettex)
The engine 'll probably upgrade (Mugello) later and i would like to use the same carb.

Dellorto? Other?
25PHBL?26PHBH?28PHBH? bigger?

Thanks

Unless you port the barrel you would never really benefit from anything bigger than 28mm.. IMO..

The easiest set up with a 42mm clubman on a std barrel, is a 22 mm dellorto/Jettex/Spaco running on or around a 125 main jet,but you could ream the 22mm out to 25.4mm and get a small increase in performance....but you will get more acceleration from a larger carb 26mm or 28mm, but dont expect a massive gain in top speed without blending all the ports and modifying the port timings.....this is only my opinion, others will have theirs...but the more feedback you get the better for you .....all the best

i use a Mikuni TM24 with a Ancilotti clubman.... goes very well

I would try a Dellorto 28 VHST but i don't find any information about the setup of this carb...

Original setup on the carb :

HD: 142
ND: S35
Mischrohr: 269HE
Schieber: 55
Nadel: D41

142 is too high for an original Stage 4....what do you think about 124 or 126?
