I got about the same results on my MC-05-127 (essentially also a 125cc).
60MPH tops, and the choke can be used to ride it in the correct A/F ratio, or run it leaner or richer.

I got 120MPG out of mine once, but acceleration sucked.
Then I switched back to a bigger rear sprocket, and the Roketa bike had a good 105MPG constant (save for longer highway rides).
The rokkie only has 4 gears tho...

My rebel 250 also gets 80MPG stock with 50% highway top speed, and 95MPG without. Stock sprockets on the Rebel are 14/33t I believe. I run a 15/25t. about as low as one can go.
If I put a 15/27 or 15/26t sprocket, I can achieve higher top speeds, but I'm content with how it rides with a 15/25 in 5th (rides butter smooth between 35-42MPH).

They have a BBK for the eliminator. A 175cc kit, that can gain 5-10MPH; is more efficient and should get you very similar MPG results, because it's lighter weight aluminum, piston and smaller tolerances..
