According to this webite: http://www.scrappydogscooters.com/139QMB_50cc_Performance.html

Your engine is the same as these KYMCO bikes (Kymco Agility 50 Kymco Agility MMC 50 Kymco Filly 50 Kymco Vitality 50 KYMCO Filly KYMCO Nexxon 50 KYMCO People KYMCO Super 8 KYMCO Vivality KYMCO NEW DINK 50 KYMCO Yager KYMCO Yager GT).

Even though you have a LIKE, you can go on these forums and see what upgraded configurations are being run. They should apply to your bike but confirm part fitment using racingplanet usa.

browncoat,

I still havent tuned the CVT so i should be able to squeeze out a couple more MPHs

You should be able to get the speed you want by derestricting the variator boss (you need a smooth boss; might as well just get an upgraded variator while you're at it), putting in a stronger torque spring, upgrading the exhaust, and upjetting. You will also need some variator weights to get the best speed/acceleration profile possible. I suggest reading all of the content on the Like 50 board. That should get you up to speed (pun intended).

Yea I'm alive. Sept 2015 got hit by a car on my 60' Vespa. Hit and Run. Broke ankle, Separated Shoulder. Vespa totaled. Kymco batt died while I was recovering. I'm in therapy now. Getting back on the Kymco, but the batt doesnt hold enough charge to turn over the engine and I'm getting tired of the kickstart! lol

Can anyone reccomend a replacement or upgraded batt for the like 50 2t. TIA

Luigi

Have fun!
