I did the VGAS flat slides kit and 18" rear wheel with a 190 from star cylce, along with other mods I did . I like it but I agree with you on modding the original carbs . I rebuilt my originals but I wouldn't switch them back. The Flat slides always gets a lot of attention. Takes a heavy wrist to operate them though.I don't think Sean Morley has a high opinion of the flat slides. You might be better off just doing a Morley Muscle jet kit to a set of OEM carbs and save your money. The guy who took over for UFO in North Royalton Ohio may have manifolds for you if you really want to do it. I think it's now Star Rider Performance 1985-2007 Vmax - Fuel Systems - VGAS - Page 1 - Star Rider Performance
I don't see them listed separately, a call or email might get you some.
From speaking w/you at Boxenstopp's in the past, I know you would like to have the bling of the VGAS-type setup. However, there's more to-it than getting the manifolds. Then you have to configure mounting them together, whatever enrichener you need for starting, admittedly not as-much of an issue here in Florida as it would be elsewhere. But then you have the cables actuation, the cables themselves, etc. Take a look at what Star Rider lists for their Keihein system. You might be better-off sending the carbs to them, and paying the piper to have them ready to-go, as a bolt-on. Also remember that there are issues related to the air filtration as-in, if you think the piece of gauze with an elastic band is gonna adequately-protect your engine, no, it won't. The scoops which fit the VGAS system may-have some filtration, I dunno for-sure. Looks like they may-not be manufacturing them anymore, as the pair they have in the online catalog is listed as, "the last one" (pair). Ram Air Scoops (85-07 All)
These boys aren't cheap: 'Mikuni' 40mm Flat Slide Carb. Conversion (1200)
