What is the difference between the 100cc kits and the 83cc kits?

The 100cc and 83cc kits have the same piston diameter (50mm), but the both kits actually only produce 83cc's. Kits that claim to be 100cc's are not actually 100cc's, so this is the first warning sign when trying to avoid inferior big bore kits.

Kits that claim to be the true 83cc's have nothing to hide, and often are of higher quality than the "100cc" kits. Are you looking for the performance kit that is also going to give you a dramatic speed and acceleration boost? This kit is one of the many performance packages offered by STG.

The STG Performance Big Bore Kit with Airsal Piston and Big Valve Head works as a direct replacement for stock parts on most Chinese and Taiwanese 4-Stroke 139QMB and GY6 engines. These kits are designed for 50cc to 100cc engines. What separates these big bore kits from all the other kits you see online?

Because of this better air flow, more power can be produced, and the internal temperature of your engine can stay cooler. The cylinder head, in conjunction with the 50mm Airsal Piston, cylinder, and high quality rings, creates a combination that is like none other. What can customer's expect out of this setup? With this setup, customers can expect to see a dramatic increase in throttle response, acceleration, and top speed.
