Ok, well is there any engine that can go bigger than a 52mm piston? And that mounts identical as the QMB139 engine?

So, looking further it looks like a 52mm piston is about the biggest I can go? does that sound about right?

I currently have a Perf. Head & Piston installed on my scoot. Piston is 44mm. Looking around it seems that it's difficult to find pistons that are bigger and heads to accomodate the big piston.
If anyone can point me in the right direction that'd be great!
Thanks.

as I'm doing more research, after I posted this, It looks like it's part of the Oil Pump.

Can you please provide assistance in identifying this part? It was behind the Generator/Stator. QMB139 Engine  |

The carb i'm looking at is 19mm.
The cam is a NCY Performance Camshaft.
And like I said, the Cylinder Kit is 50mm..
I know all this I've listed is Engine... I'm not really sure what i'd need for the Transmission, If anyone is willing to let me know, I will take some tips from Larry's post aswell..
Thanks.

I am currently looking at upgrading my QMB139 Scooter, I believe it's a JSD50QT-13 Scooter.
I'd like to be able to pull around 50-60MPH. I currently have a few Parts lined up for an upgrade could you tell me if what I have planned will get me to the speeds I want?
Performance Exhaust
Carburetor (CVK,19mm)
Cylinder Head(81cc)
Cylinder Kit(50mm)
Air Filter
CamShaft
Decompression Tube
I plan on getting these parts from scooterworks.com
Also, I do need some new body panels and have decided that I'm just going to replace all Plastic on the scooter with new,same color pieces. Can anyone recommend a good seller for the Body Panels?
