RGS/ SFC inlet manifolds cracked again!

I have a pair of similar looking manifolds that were bought about 35 years ago and have been in my storage box. Pretty sure they're off a 650 Yamaha or similar - they are good for the 39mm Keiihin FCRs I'm fitting (with a slight stretch) and I reckon they'd fit the triples. Excellent quality rubber. I'll be looking for more for bike #2.

Now you have got my attention are you able to upload a piccy or two please... Would be great if there were an off the shelf solution

I ended up using custom made inlet stubs mated with Husaberg sourced rubbers for the 39's, for the 35's it was a whole new ball game and they seem to work more better to boot

Brett, these are for an SF, so may not be relevant for triples - but may be a possible solution - they were a bolt on fit for the twin. I'd would have thought there are plenty of japanese motors with suitable rubber carb stubs that could be adapted?

Arr side draught FCR's now they do look sweet........ am using down draughts on the triples must put together a how to one of these days.
 
I've built two pairs out of a set from a GSX1100 Suzuki. A lot of work to create the linkages and split them into four individs and then set up the shafts for a twin. But they will be worth the effort!

How about something like this? Genuine parts, very low cost ... suitable for 40mm inlets ... if not these, there are loads of others to trawl through.

Nice set of adapters and inlet rubber stubs for Mikunis available from Tophams for the triples.  Adapter plates need to be machined to a straight 36mm if the inlet port is modded, otherwise tapered to fit the stock ports.  I can supply the complete kit with all necessary fasteners, machined to requirements.  A bit pricey at ?195.00 though.

I haven't checked recently but Sudco used to list a bunch of the molded rubber inlet manifolds. They had them by application and also gave the dimensions. Had one of those on my Norton single carb conversion kit.
 
Hmm an adaptor plate now that's a good call, brilliant, .hmm there are loads of plate manifolds here just nought plug an play.

Now back to the search in hand for ones to bolt straight onto the Lav head for use with good ole Dell's ... well there is at least one of us who still seems to want to run em.  :o

I know easiest solution is to pick up the old ode cologne and give Red a call for a set of flash new Mikuni's but where would the fun be in that hey ?
