* "Hi the enthusiasts of the KZ! The standard original cylinder on a TM R3, it is a real piece of Swiss watchmaking. The factory nicasil coating is of a remarkable quality, but for that it outsources its cavalry and lasts for a long time, the assembly request Absolute rigor.
My essential mechanical trick for replacing a KZ-R3 cylinder: the pairing of the piston and the break-in in good standing !
When you install a standard new cylinder, never put your old piston or a piston taken at random. Measure the exact bore of your new cylinder (often delivered in original dimension a) and choose a TM original piston with the operating game recommended by the manufacturer (usually around 0.08 mm to 0.09 mm playing skirt / shirt according to your preparation preferences).
Second Vital Point: bROGING !
Even with nicasil new treatment, make 2 gradual break-in sessions: a first 10-minute session on trolley / track without exceeding mid-speed to mount the set in temperature and control the absence of water leaks, then a session in progressive track with a gradual load with a mix. Slightly richer in oil (4%). A well-applied and prowling cylinder in the rules, it's constant handle-handed watts insurance! "*
Drain the cooling circuit of your TM KZ-R3 engine. Remove the exhaust pot, the cylinder head, cylinder head and 4 cylinder base nuts. Drag the old cylinder upwards to release it from the piston.
Clean the joint range from the motor housing with brake cleaner. Protect access to the bottom-motor with a clean cloth. Inspect the rod set and replace the piston axle needle cage.
Follow the tip in Michel: Install a new original piston from the standard cylinder. Place a new base joint, slightly hose the NicaSil shirt with 2T competitive oil, and gently insert the cylinder over the segment.
Tighten the cross-coded nuts to the couple recommended by TM Kart. Reassemble the cylinder head, make the squish control measurement over tin thread, put into water and carry a careful purge of the cooling circuit.
Q: What does "Standard" mean for this TM KZ-R3 cylinder ?
A: The "standard" designation indicates that the cylinder is delivered factory raw with diagrams, ducts and Nicasil processing compliant with the TM Kart official series model. It has not undergone any preparation, editing or modifying a subsequent diagram, making it 100% in accordance with the approval regulations for official competitions.
Q: Does this KZ-R3 cylinder rise on the housings of a TM KZ-R2 engine ?
A: Although R2 and R3 engines share a near architecture, the R3 cylinder incorporates developments at the transfer and exhaust levels. To fully exploit the potential of the cylinder R3 and guarantee a perfect alignment with the housings, it is recommended to use it on the dedicated R3 bas-engine or check the alignment of the transfers when mounting on an R2.
Q: Is the cylinder delivered complete with the piston and seals ?
A: No, this article only includes the nicasil nicasil cylinder of TM KART origin. The piston, the needle cage, the base / cylinder head joint pouch and studs must be ordered separately (or recovered if they are new).

The Copper cylinder head gasket 0.03 mm is a piece of mechanical goldsmith. Intended for the most advanced competition settings, it adjusts the squish At its limit value when standard thicknesses (0.10 or 0.05 mm) are too important for the desired room volume.
At this thickness, the seal acts almost as a direct contact interface, offering the best possible thermal conductivity between the cylinder and the cylinder head dome.2 0.03
Adjust the compression ratio and the dynamic behavior of your gearbox engine with the Combustion chamber (cylinder head dome) origin TM Kart for KZ-R2 and KZ-R3 engines. Key element of the high motor, the profile of this dome directly determines the volume of the chamber, the height of SQUISH and the combustion speed of the air / gas mixture.
CNC machined with micrometric precision in the workshops of the Italian factory TM Kart, this room guarantees optimal thermal dissipation and a perfect centering in your cylinder head. Proposed in different variations ranging from 3.3 to 3.6, it adapts both on the block Kz-r2 only on the last Kz-r3. It allows you to change your motorization according to your needs: lower dimensions (3.3 / 3.4) To promote explosion, couple and slow turn output, up to higher ratings (3.5 / 3.6To release the top plans, offer an exceptional straight line and prevent the risk of hot weather detonation.
Maximize the ignition efficiency and power of your engine thanks to the bougie BRISK SILVER L08S ignition. Specially developed for the extreme requirements of motorsport and competition karting, this bougie is a real reference for exploiting all the potential of the trademark engines Tm kart (Categories KZ with gearbox and monovynesses).
Its peculiarity lies in the use of a Central electrode in pure silver. Money is the best electricity and heat conductor of all metals (even exceeding platinum and iridium). This property allows the BRISK L08S to deliver a spark of a remarkable energy with a lower voltage, while dissipating the heat accumulated in the high speed combustion chamber. This results in a faster flame start, a more homogeneous combustion of the air / gas mixture and an extremely frank accelerator response throughout the range of use of your TM block (KZ10 to the latest KZ-R3).
