TB 143cc Bore Kit & Performance Camshaft – Z125 2017+ Models

143cc/60mm Big Bore Kit with Performance Camshaft:

TBparts 143cc big bore kit with our NEW bolt on performance camshaft kit. The combination of these parts amplify the results! The cam opens up the valves more so the larger bore kit can breathe better resulting in even more power throughout the power curve! You will not believe the night and day difference this setup makes over the stock engine! 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). The domed high compression piston (10.9:1 pump gas friendly) and complete head gasket kit set this kit apart from other similarly priced 143 kits on the market. Our camshaft grind has years of R&D built into it too. Gains are 20% over stock throughout the RPM range unlike most other cams that shave power off the bottom end to move it all up-top. Not to mention this camshaft is brand new, not a regrind, and includes brand new Taiwan TPI bearings made to OEM specifications. This is an affordable way to make your Z125 engine race ready and a lot more fun to ride!  High quality parts and requires no machining to the cases or other modifications – bolt on Tune and go!

• Ceramic coated all aluminum cylinder (no steel sleeve)

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 having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki dealer. We also have a link on our website in the INFO section under KLX110 where you can download a free shop manual (klx110 engines are very similar). The parts are installed in the same manner as the OEM parts.

Note – Bolt on kit for 2017+ Kawasaki Z125s. Camshaft kit is for use with the stock cylinder head this is not a decompression cam like OEM, but will not affect starting. Fuel system tuning will be required for optimal performance and to avoid running lean. Our cam requires removal of the rear bearing for these model years.

Kit contains: TBW0305, TBW306, TBW0377, TBW0378 TBW1431, and TBW0645
