I think what you have is a AF16 (94-01 SA50) engine that someone swapped into your aero. They then removed the gears and cover from your original AF05 that came on your aero and put them on the AF16. Like I said from the pictures the following parts appear to be off from a SA50
Intake
Carb
Cooling shrouds
Rear and front rims
Airbox
Kick start

Yes, but the early SA50 Elites also ran an AF05E, as did the SE50 Elites. The engine number needs to be looked up but my source book got stored when I was not looking a month or so ago.

As I stated before when they swap gears out of the AF05 into the AF16. Swapping the gears from the AF05 which I think are 10:1 is a cheap upgrade.

Can be reasonable cost, but takes tracking down the correct model. Of all AF05's, only the '87 SE50 got 10.2:1, and only the non-restricted version. The rest of the AF05's are about 11.1:1

Alright Im lookin to drop in the 72 polini corsa, $350. I think that price is a little steep but thought I'd ask the pros on if that's the going price or can I snatch one for way cheaper?

The trans cover that was originally on the motor will verify it's an af16

it would appear to be a af16 that has had a af05 gear swap it may well have been done to retain the original engine code that matches the papers rather than a mod for performance

So its an af16 with af05 gears n cover you guys say. Also I was trynna figure out why it doesn't pull after about 33 mph. I pulls strong till it hits about 33 and then it just stops, like it runs outta power. Its still screaming but not pulling like it should. Any suggestions?? Its still stock carb but running a #95 jet, also has 9g weights.
