Could you take out the petal and reed stop from the original reed cage and then cut out the middle and then mount the new manifold on top of the old reed cage?
Remove the entire SE50 reed cage assembly and leave it out. Mount the CT manifold to the adapter plate and the adapter directly to the block.

The CT reeds are doubled up in a "V" shape. The case port isn't deep enough to fit the CT reeds. Do as The Bear suggests. I did this on 2 different SE/05 blocks and it worked very well once an adaptor is crafted. Pity nobody has seized on this opportunity to make a batch of adaptors with a CNC machine. I'd pay $30 for one if I needed to modify an Aero.

Sure you need an adaptor. Are you saying "the adaptor plate" exists?

No.....you have to make something custom.

Any merit to removing the reed from stock reed cage and widening out the hole? They're probably a bit too fragile and maybe it's cheaper to manufacture one from aluminum but I've already got one

None worth the effort. All using the reed cage does is make the intake tract longer which might help the bottom end a little but the top end will be hurt by the restriction the stock reed cage creates and then you might as will skip the CT and the OKO. Any bottom end boost will be negated by the CT and the OKO, so just make an adapter plate. It will take an hour at most with a drill and a file or two. Or just use a piece of sheet metal. FYI, the material the reed block is made of is very fragile and will probably crack or break on you if you try working on it.

I'll see what I can fabricate before I go and buy a manifold and get back to you guys as I go. Maybe a thin piece of aluminum

The plastic reed block is as fragile as The Bear suggests as well as too tall.
In addition, assuming you could hollow it out without breaking it, I'm not sure it would be stiff enough to maintain gasket seal without the metal backing of the stock-shaped manifold.
Scooterwerx used 1/8 or 3/16 thick flat Alu billet.

Price for 1 would have to pay the Cratsman's time in measuring, slicing and boring.
Might take 2-4 hours, depending on skill and machinery used.

CNC could knock out a dozen very quickly once dimensions are input.

I'd gladly pay $30 if I were modding an SE/05. The 65cc Polini ran nearly/over 60 with 7.83 gears and a 24mm CV carb.

Looking for a jets set for this carb http://cgi.ebay.com/ebaymotors/Honda-DI ... ccessories

Where can I get a set and what range of jets would you guys suggest?

Are these the right type? http://cgi.ebay.com/SET-10x-MAIN-JETS-T ... 27b9e5311d This also looks like the range of sizes I'd want

Main jets

I would try the 24mm OKO with a 48 pilot 120 main. But I am no jetting expert. :confused:

Should of specified my needs. I'm assuming this is what you'd suggest for normal riding. What size for a cylinder break in?

:confused: The same size? Maybe just mix in more oil. 32:1 and no WOT for the first few tanks.

Thanks! you responded faster than I edited my last post. Maybe I'll buy the 120, one size smaller and one size bigger. I know it's hard to give some one an exact number because of all the possible variables.
