If looking for easy bolt on power, this big bore and carb
kit is it! Works great with your KLX stock head, our Race Head, or our new V2
Race Head.  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). We top off the bore kit with a 28mm performance carb
kit that is easy to tune and works great with this large bore kit.. 
Additionally, our head gasket kit also 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 with
this 165 kit (available in this section).
