I have a Windmill airbox and I'm not sure one piece branch pipes would work.
They do, I have them on my Patrol.
Hmmmh do they work with Raceway perch rings AND the most awesome airbox ever constructed? :mrgreen:

I don't use the perch rings, they seem more secure than the 3 piece branch pipes, and they've never come off, so I can't say if they would work, or be of any advantage.

I have the perch rings and the 1 peice branch tubes on my 2010 carbed setup and they work fine, never had a problem so far. ( 85,000km's on the clock). :)

I had an interesting experiment: Jim Pettiti talked me into all his must haves...and they worked. Phenolic heat blocks/mikuni manifold/perch rings......+++
In 2015 we pulled an abandoned 2007 Tourist out of a barn...Carbs were green from algae. The fitting that went south on Eastblock's rig too were both shot. So I mounted mikuni manifolds (as Jim used to call them) without heat blocks....they lasted about 5000km. then the new owner put russian units without heat blocks.....they were totally leaking after less then 2000km. You actually could see and hear them breating.
On my own rig which has the phenol heat blocks and mikuni manifolds the first very tiny leak appeared at 39.000km. One thing you cannot trust totally on are that the phenol heat blocks would stay flat and sealed. Over time they deform. Never use silicone there, gasoline will swell it! I used teflon paste (Laco Slicktite: red flask) which did work well between cylinder head and phenol heat block and between heat block and Mikuni manifold.

Interesting. I don't think I've ever had problems on that end of the carb, but I sort of missed the Keihin years going from Mikuni to FI (not counting the Wolf, but I had no love for that bike and didn't ride it enough to care). I only now have the BC with Keihins and TerryG had set it up nicely, its branch tubes are doing OK.

I've never had any trouble with the branch tubes coming off, I'm sure the perch rings are better, but I never found them to be necessary.
I'm also still running the same three piece branch pipes from 2005/110K kilos, and the same Mikuni compliance fittings since 2008, with no phenolic heat block. I have a set of phenolic heat blocks since right after I put on the Mikuni compliance fittings, I keep saying "I'll put them on, next time I replace those compliance fittings" but I've yet to do so. Maybe it would run better with them, I don't know.
Contrary to what Sven says above, I used black high temp RTV silicone on my compliance fittings, with no adverse effects.
I do cary spare compliance fittings, probably why I've not had any trouble with the ones on the engine :lol:

Happy trails,

Jaybird,
it might be "Possibly A bit" colder in New Jersey then in Costa Rica....that would explain that your Mikuni manifolds lasted longer then Ely's (2007 Tourist I talked about) When I put red Permatex silicone on her sucked Russian manifolds, she told me that she just got home. Already the next day on her way to the workshop returned the sucking sound and popping. (might be that gas leaked over night out of the carbs)
And you may be sure that you scare off Mr Murphey by having spares at hand. :mrgreen:

Here's what I got from Amazon. They're the same as we used for Mikuni carbs in the CMSI days.

These appear to be new stock. Contrary to appearances these also have a metal block embedded in them, it's just completely encased in rubber.

I'll see how they fit the FI throttle bodies and check back in. The price is certainly right and the quality on these is top notch, so I'm hopeful.

Only had one experience with the Mikuni's and found them to be soft causing the carbs to oscillate and rubber ripping/cracking early.

All compliance fittings eventually fail in my experience.

I ran Mikuni for years and find them no more susceptible to failure than KOK or the off-brand varieties.

Thicko question from the back of the class - aren't the carbs also supposed to be supported at the back end by the intake pipes from the air filter box? So shouldn't "flap about" :D
