Slow Spree

[sleeves]

So my Spree has only been running at about 20 MPH since i got it. It was sitting for a few years so i have been cleaning everything
to find the issue and trying to get as much info of this site to find the problem. Still no luck but today i pulled off the air intake boot
on the carb and my scooter was flying easily reaching 30 but with the boot on im going 20 max. My air filter box is clean the holes
are not clogged i have a new air filter on it. Anyone have any info with this and what could be my problem? Have put so many hours
into this to so any help would be appreciates thanks.

Sounds like jetting. Is everything stock? What do you want from this bike, just 30 mph top speed? If so, you can burn the carbon from your muffler w a torch to unclog it (or buy a new one) and try buying a jet kit and a carb rebuild kit and going going to town.. a good running spree stock will do 25-30 or so from what I understand.

But it might be better to swap over to a complete running motor that comes w a 2-speed trans like an af16 or af18 or even a later afo5 w a variator. A stock aero 50 afo5e will do better than 40, reliably.

If your spree runs good without the stock air box get a free flow filter. It is odd for a stock jetted spree to run without the airbox. Did you ever re-jet the carb at one time?

Ya...
Maybe bystarter is leaking or stuck open?

That sounds like it could be the issue. It would need to be super rich for it to run with the Air box off. This or the clogged pipe that was already suggested. Do the bystarter vacuum test that's in the manual. Then bake the pipe

Probably bake the pipe anyway haha it collects stuff easy.
