Nope, I personally haven't, but I take it that you'll be running it?
Can you keep us updated on how it worked for your application? Thanks!

i have 2 of them, one that broke upon installation and one that is on the non running scoot now.
one definate tip. both of mine came with a very uneven mating surface on the stuffer side. tape some wet dry sandpaper down to something flat and lap the bottom completely smooth. as well i found that it was better to coat the stuffer with silicone gasket maker and install with out the stuffer gasket. like the ct manifold you want to coat the vacuum nipple with jb weld and re-torque as these are notorious for leaking.
all that being said, so far it seems like a decent quality piece, especially if you want to fit an aftermarket carb under an aero 50's body work. mine clears (just barely, but thats all i need) with the OKO chrome airfilter that treats sells as well. now i just need to get all my carb issues sorted out so i can put the thing to use.

PS, another tip. this manifold is shorter than the CT, to get it to fit (atleast on a SE50) with an OKO you need a 1cm or so spacer that goes under the reed block (if your running a SE50 you are going to need one anyways) or on top, to allow for the float bowl to clear the belt cover "nubs".

Actually Loc-tite would be a much better choice than JB Weld to secure the nipple.

this is probably pretty true... once you jb weld it in to seal and secure, its probably never going to come out, even if you want it to.

Thanks turtle, I mainly got it to experiment with and I can always use it on another build if i dont like it. Trying to solve my idle problem on my Eve and I am willing to bet it is my manifold leaking somehow so I thought I would try this one since it has fewer places for potential air leaks also its a shame to have daytona and polini reeds for stock cages and not be able to use them :D I sanded all the surfaces smooth on my CT, JBed the nipple, and made new gaskets recently and the idle seems to respond better but still requires a larger pilot, I know it is rich at idle because I hear a popping/misfire at idle from the air filter but it wont idle worth a d*** without it being rich so the only conclusion I can reach is an airleak somewhere even after i have done everything to seal and prevent them.

I saw that manifold when i was shopping for an intake, but i went with the CT because it included the big reed cage.
