Upgrade from 50 cc to 60 cc?

Hello I have a Kymco K-pipe 50 cc

It drives quite well and reliably but in terms of performance it's not powerful enough for me.

I want to install a 60cc piston. What other parts do I need, a new carburetor or main jet, etc.

I already have the CDI out and a short throttle slide in but I want to set it to the highest level, whatever is possible, no matter whether exhaust, manifold or air pipe, give me tips on what I can do, thanks

Why not directly 70ccm? So you should definitely adjust it as the main nozzle spring and weight otherwise it can come quickly to a feeder

Sorry didn't know that was a switching moped. Well, I find no 70cc cylinder or 72ccm because otherwise it wouldn't fit, I don't think it would be made. Although you could install a 60cc cylinder, it actually brings you almost acceleration. Did you get all the throttles out? In any case, you should then install a 16 or 18 carburetor in a larger cylinder. Since the cylinder actually brings you almost only acceleration you can add tuning exhaust Here https://youtu.be/4eMDvd_wVrI Dvd_wVrI (spul on 2:00 ahead) Can also watch multiple tuning videos on the channel. Since you needed a link for the cylinder: https://www.amazon.de/dp/B01N6QPUD2/ref=cm_sw_r_cp_apa_sYfwBbCVGDTC6 C6

Yes is wrong because it wouldn't fit around 0.2mm or something. https://zzip.de/forum/viewtopic.php?f=152&t=16932 2 Others also have the problem that they do not find 70ccm. One has one but you have to write via PM, can try. And you shouldn't worry about the crankshaft if you get a 60ccm. At 70cc you don't have to, but then the engine stops longer.

For half a HP more, I would not risk driving without a driving permit (force!) and without insurance protection as well as without an operating permit.
