Overview
Description
165cc Big Bore Performance Kit (64mm):
- Ceramic coated all aluminum cylinder (no steel sleeve)
- Lightweight high compression domed 64mm piston with rings, pin, & clips
- Head gasket kit – Now includes the cylinder head o-ring set and an exhaust gasket.
The all aluminum ceramic coated cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). This new cylinder along with a complete head gasket kit and domed piston will provide the extra power to make your new Z125 a lot more fun to ride! These are high quality parts and definitely will dramatically increase the power and fun factor on your bike!
Important Notes:
Cylinder skirt is 66 15.1mm, bore case to at least 67 x 16mm to accept cylinder skirt.
Installation requires engine dis-assembly and case boring. Therefore, we highly recommend a professional technician install this kit and the cases bored by a reputable machine shop. Its also recommended that a professional technician make sure its tuned properly once installed. An aftermarket fuel controller is required and possibly an autotune will be needed to prevent a lean condition and damage to your engine. Additionally, a performance exhaust is also recommended as the stock exhaust is restrictive and may cause your engine to run hotter.
