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 set this kit apart from other similarly priced 143 kits on the market. Affordable and will make your Z125 a lot more fun to ride! High quality parts and requires no machining to the cases or other modifications - bolt on and go!
IMPORTANT NOTE: Any bore kit for the Z125 must be used with an aftermarket fuel controller to prevent a lean condition and damage to your engine
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 in this section or from your local Kawasaki or Suzuki dealer. The parts are installed in the same manner as the OEM parts.
