GY6 150 Ceramic Big Bore Kit for 150cc GY6 Engines
This kit comes with cylinder kit with piston rings, wrist pin and circlips along with a 61mm/62mm head with larger valves with high performance cam shaft. All parts in this kit are brand name and NOT brown box from China as a matter of fact they are NCY, MRP, Naraku name a few. Your order will include two of the above depending on stock. All we have found to be produced in the same factory and branded.
Cylinder Kit and Piston are 58.5mm All Ceramic with ultra smooth bore and ports that simply add the fuel and air flow an iron cylinder can not. AS in the two stroke kits we sell the difference between kits are the ports and metal used to produce the cylinder and piston. The 58.5mm cylinder kit produces the power of a 61mm iron kit.
The head is either 61mm or 62mm depending on stock.
Cam Shaft is low end power and all around performance.
To get what this get will provide in power a quality unrestricted variator is needed. The DR Pulley Variator Kit gets the job done with 12-14gram sliders if a torque spring of 1500-2000rpm is used. Use 10-11gram if no torque spring.
Your carb should be at least up-jetted with main and pilot plus air filter. The Fuel and Air Cold Intake upgrade offered is best.
