165 Bore Kit - 4 Valve Heads

KLX110 Engine
Item no:  9178

Qty: - +








 

165cc Big Bore Kit for 4 Valve Cylinder Heads:

- All aluminum ceramic plated 64mm cylinder
- Lightweight short skirt 64mm 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 option to increase the power of your engine. The kit includes an all aluminum ceramic plated 64mm cylinder which will increase your engine displacement to 165cc.  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 very lightweight short skirt high revving 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 definitely will dramatically increase the power and fun factor on your bike!

IMPORTANT NOTE: Installation requires engine disassembly and case boring. Therefore, we highly recommend a professional technician install this kit and the cases bored by a reputable machine shop. If you plan on installing the kit yourself, we highly recommend purchasing the shop manual for your bike available in this section or from your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the OEM parts. Also, while the engine is disassembled, you might consider the following options:

- 4th Gear Shift Drum (available in this section).
- 2008 Kawasaki Output shaft - a must if you have a 2007 or older model (available in this section).
- 55mm Stroker Crank - this will increase the engine displacement to 177cc when used with this 165 kit (available in this section).
