TB 143cc Bore Kit - For 4 Valve Heads [TBW9076]


Product Information

143cc Big Bore Kit for 4 Valve Cylinder Heads:

- All aluminum ceramic plated 60mm cylinder
- Lightweight short skirt 60mm 4 valve piston with rings, pin, & clips
- Head gasket kit - includes the cylinder head o-ring set and an exhaust gasket.

This bore kit is designed to work the Kitaco and YX (Dirtmax) 4 Valve Cylinder heads and provides you with an additional bore size option to use on your engine. The kit includes an all aluminum ceramic plated 60mm cylinder. This 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). Also included is a lightweight high revving 4 valve piston. Finally, our head gasket kit includes a head o-ring set and exhaust gasket so you don't have to re-use your old ones or make a trip to your local dealer to get new ones and spend more money. These are high quality parts and no case boring required - bolt on and go!

There are no installation instructions, but if you can replace your piston, you can install this kit. If you don't have any experience working on your engine, we highly recommend purchasing the shop manual for your bike available or from your local Kawasaki/Suzuki dealer or having a professional technician install the kit. The parts are installed in the same manner as OEM parts.
