TB Parts 170cc Big Bore Kit w/ High Performance Mikuni VM26 Carb and Cam
Fitment:
Kawasaki KLX140 (2008-2020)
Kawasaki KLX140G (2017-2020)
Kawasaki KLX140L (2008-2020)
Kawasaki KLX140R (2021-Present)
Kawasaki KLX140RF (2021-Present)
Kawasaki KLX140RL (2021-Present)
These parts work great together for an unmatched performance increase. Starting with the complete big bore kit you get a lightweight high compression piston that is 5mm over stock making close to 50% more power.Add the 6mm larger VM26 carburetor (that utilizes the stock air box) and the bike will not only start up and idle better but it also feeds the engine more air and fuel to make more power through the powerband. Then add the performance cam and the bike will start making even more power at 5500 RPM and carry it to the top end for even larger gains. Turning your KLX140 into a race ready machine or a backyard sleeper! This is one of the best, if not the best kit you can run on your KLX140 to reliably wake it up without breaking the bank.
Kit features:
Huge power gains at the best price!
Aluminum cylinder with steel sleeve (63mm)
High compression 63mm piston with rings, pin, & clips (Safe on 91+ Octane Pump Fuel)
Top end gasket kit
Genuine Mikuni VM26mm Performance Carb (Not a cheap Chinese copy carb)
Intake Kit port matched to the VM26 and stock cylinder head
Main Jet kit (Stock Main Jet size is a #190 – Extra jets sizes 140, 145, 150, 155 (x 2), 160, 165 (x 2), 170, 175 (x 2), 180, & 185.)
Extended Throttle Cable for use with the stock bars and throttle or tall bars.
Brand new camshaft and bearings
This kitdoes NOT require boring of the case– simply 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 having a professional technician install this kit or, at a minimum, purchasing the shop manual for your bike available from your local Kawasaki dealer. The parts are installed in the same manner as the OEM parts.
Installation note: KLX140 camshaft bolts are reverse threaded, turn them right/clockwise to loosen/remove.
Tuning Note: A good starting point for the jetting is the stock #22.5 Pilot and #175-180 main with the stock pipe. Aftermarket pipes may need to go with the #180-190 main jet.
