Hey All,

Having some issues with my 09 Zuma 50L 2 stroke, hoping you can assist.

When I bought the scooter used, it had good pull throughout the entire power band and could easily hit 40mph on the speedo on flat ground. Now, I’m struggling to go above 20mph on the speedo on flat ground. It’s basically been rendered useless.

I’ve done the following to try and fix the issue.

Cleaned and serviced carb.
Replaced vacuum fuel petcock with manual petcock.
Removed fuel filter from carb and replaced with inline filter on fuel line.
Replaced gas cap (old cap fell apart into gas tank, I removed all parts of old cap including screws, springs etc).

I’m at a loss. Thing went from running well to having absolutely no power. Any help is appreciated.
