We appreciate your enthusiasm for your scooter!
Perhaps we could try sentences and punctuation in your future posts? 
Your posts might or might not be responded to by other owners - but it would be easier to follow your comments.
Posting under any of the 50cc headings with the name of your scoot in the title - should get some responses - if there is interest here?

Eyup!

Many moons ago I had a Yiben YB50QT-6, which is very similar in form;



In honesty I found it very well built and kind of regret letting it go, but I feel that way about most of my bikes I guess.

The problem is that it was probably 7/8 years ago but I'm happy to help if you've got any specific questions. I recall it being quite robust, and if it's got the standard 50cc GY6 (139QMB) engine in it you could always pop an 80cc head and barrel on and zip about happily.

I'm on the lookout for a Kymco Agility myself, which isn't a thousand miles from what you've got!

The "sf10" is a 50cc Kymco version of the Chinese 139-qmb engine.  It's almost exactly the same as a 139-qmb, and all parts are interchangeable, including Chinese speed parts..  However, the qmb-139 doesn't have the Kymco attach point for the Kymco rear hugger fender.  It's easy enough to fabricate a small bracket to hold the hugger fender.
