Greetings:

Jet sizes don't apply when you switch carb models/sizes. You might actucally need a larger jet than 85 in the bigger carb. The engine inhales the same amount of air through a much larger venturi = less negative pressure over the jet =need a larger-sized jet to deliver sufficient fuel.

I'm not sure that honker carb was the right call for 65cc. Hope I'm wrong.

the jdm af28 carb isnt that much larger than a stock carb, the slide is actually close to if not the same size, its just the inlet is larger. i would definitely still upjet it, to at least the jet polini includes...the cylinder is easy to install, just reverse the process of disassembly and be generous with the oil on break in!

Here are a few pics....

This is the mount fixed and the frame reinforced just to be safe

The almighty Polini BBK

Here is the Super Dio intake manifold and carb test fitted

Here are a couple of pics showing the differences between the Super Dio(left) and the SE/05(right) carbs

Close up of the carb: I take it the brass colored fitting is for fuel and the silver for the oil supply?

Side Kickstand welded and functioning

This is the color I'm painting the scoot

Its like a flat olive. I was thinking powdercoat the wheels either bronze or black but not sure yet

Painted the kick cover

Still waiting on the Daytona Exhaust from HondaCharlie........

Nice work. I noticed something in your pics that makes me take back my previous post about the ZX Carb. Measure the carb throats on the o-ring sides and let me/us know what you find?

Also the Jet that came with the Polini fits this carb but its only an 83.

Thanks to VeeDub for the link for these jets for this carb:

Thanks Toast that means alot to me

Thanks for the interest but I'm gonna hold on to this one. Gives me an excuse to look for a 94+ Elite

BTW This is the contessa kit

brass is gas and silver is oil line from pump just like an elite.

this is an se50 engine right? what reed/manifold did you use to get rid of the gap?

Wheelman-111 · Post by **Wheelman-111** » Tue May 05, 2009 9:09 am

Greetings:

The oddball 3-petal reed from the '87 DJ fills the gap but still takes the SA16 manifold, at least on mine it did. Not sure if the design provides the best flow, but it fills in all the cracks and works at least as well as the original mani - which points the carb mouth at the shock.

Perusing parts fiches and switching from NB50 Aero, SE50 and SA50 Elites in '87-'88 US model years is very informative. Someone said the '88 reed block serves as a bridge adaptor between old/new and I think that's correct.

All of the holes lined up so I'm thinking yes but I'll take a pic of the gasket on the block for you this weekend.

This is an SE50 engine. I used the same oddball reeds that wheelman has. They are 3 petal ones off of the Super Dio manifold. They look to be carbon too but not 100% sure. They definately arent metal.

I also just got the Dio cable (thanks evilone) that slides into the cap but I noticed that it doesnt clip into place or anything which I thought was weird. It stays held up @ the carb top just by the tension of the spring between the slide and the top? I went ahead and raised the needle to the bottom notch which should have me @ the richest setting. Thats what the Polini BBK instructions said to do.

Here you go VeeDub:
