whats the difference between these 2 engine top ends and crankshafts are they interchangeable or if not can the dio top end be made to fit the 87 aero engine

im a mechanic so it any machining needs to be done no problem

it would be great to have a bit more power

Bore/crank aside, the main downfall of the AF05 is the lack of trans parts.

He's talking about the variated AF05E engine, not the unvariated Spree AF05E engine.

Can you put longer gears in it? Taz's maybe? Is the clutch the same (able to take new springs all over)?

i just put an italjet dragster clutch it fits perfect

i can change my gearing more ways than one
its not on a scoot i have the engine on my 1977 moto bm moped frame


the scooter it was on was trashed i found it in a dumpster it looked like it got run over but the engine runs great

Cool!
I've always wanted to see a sit down scoot motor
rigged to a sprocket powering a moped.
Did you do a ruckus variator yet?
That will give you more speed

Different bore, stroke, wrist pin, the intake ports are different, crank is different

The short answer would be NO, you can not swap top ends.

Can you show a picture of where there is a sprocket instead of a wheel on that moped of yours?

Indeed, would love to see the
sprocket and what you're geared at.

It's on the far side (right side) of the bike in place of where the wheel would mount on a regular scooter..

I know where it is , I want to see it better.

That doesn't look like an aero tranny cover....
Am I mistaken?

Say are you the moped jay on MA? If so, you OK after the accident?

il take some more pics of it today

yep im the same mopedjay im doing alright still in a lot of pain and im having knee problems but i guess i should be a lot worse after being run over

Really interested in a few picts of the sprocket setup.
Pretty please?

i still aint gut no sprocket on it yet

im planning on using a tomos moped wheel sprocket on the engine
24t on engine and 34t on wheel will give me around 1.4:1 that should make up for the bigger back wheel

i finally got spark back and went through all the wiring to get rid of everything i dont need all i want is headlight tail light and engine spark dont need the other 5 pounds or wire
