Ultimate carb set up GS-5/6

[Kara25]

What would be considered the ultimate carb to run on a gs550/650 hybrid engine? Top end is stock 650 with a marving 4-1 racing exhaust. Just finished installing an oil cooler and i wanted to have an idea what people who owned 650s or made hybrid motors like mine run besides the stock Cvs with a dynojet stage 3 kit like i do now.

GS750's came with BS32 carbs, so your 650 should be getting plenty of air. Do you have a proper free flowing air filters? Real deal K&N's, or similar? Honestly, you could go down the rabbit hole with RS34's, or BS34's, working your ass to get them tuned for the bike, in the hope of picking up a few hp, or you could just enjoy your bike for what it is.

Yeap i have stock BS32SS CVs with a Dynojet stage 3 kit and K&N RC-2382 dual lunchbox airfilters. What about the Keihin roundslides CR-29s?? I see them in a variety of motors from gs750s to cb650s etc. I get the idea that you dont need a too big of a carb to maximize the effects and not <<drown>> the motor Nessism

Those Keihin's are $1000 (USD). Do you think 2-5 hp (at most) is worth that much? Not to mention, all the hassle of jetting them?

Money is not the problem but i get your point. Especially the jetting chase cause from what i gathered jets for those keihins are not so easy to be sourced at least where i am living
