Description
TB Parts 187cc To 201cc Big Bore Kit For YX/GPX/Zongchen Engines
Item #TBW9144
*** Case Boring Is Required To Install This Kit! ***
TB Parts 187cc to 201cc Big Bore Performance Kit (67mm):
- Ceramic coated all aluminum cylinder (no steel sleeve)
- Lightweight high compression domed 67mm 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 bike 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:
This big bore kit is recommended for use only with our V2 Race Head. For all other applications, please check clearances.
This kit is only for the YX/GPX/Zongchen 150cc to 160cc engines witha a KLX110 type topend. The increase in displacement will depend on your stock engine size.
On most engines, 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. Besides the case boring, the parts are installed in the same manner as OEM parts.
