* "Hi Watts' enthusiasts! A Cylinder R3 Full Black Prepared, this is what is more sharpened on track. Reworked lines and optimized diagrams allow the engine to breathe at full lung, but beware: a high Prepared motor requires a clock care at editing !
My essential mechanical trick for this Full Black cylinder prepared: the fignolate of the carburation and the squish !
Who says prepared cylinder said accelerated air vein speed. Do not keep your carburized settings with a standard cylinder! During your first rolling, lightly enrich your main nozzle (2 to 3 more points) and adjust your needle / needle to secure the break-in and observe the engine behavior.
Second crucial point: the squish. A prepared cylinder is fully expressed with a squish set to the tenth of a millimeter. Associate this cylinder with a suitable cylinder head (such as TM 3.3 to 3.6 domes depending on the weather) and take the time to measure your tin value accurately. With a squish stalled with small onions and a fitted carburation, this Full Black cylinder will deposit the end-line competition! "*
Drain the cooling circuit of your TM KZ-R3 engine. Remove the exhaust pot, the valve, the cylinder head and the base nuts. Slide the old cylinder up to clear it.
Clean the seal range perfectly on the motor housing with the brake cleaner. Check the condition of the rod and replace the piston axle needle cage.
Follow the tip in Michel: Mount a new original piston paired with the cylinder. Install a new base joint, hose the NicaSil shirt with 2T competitive oil and gently slide the Full Black cylinder over the segment.
Tighten the cross-sided nuts to the couple recommended. Reassemble the cylinder head, make the squish control measurement over tin thread, put into water and carry a careful purge of the circuit.
Q: What is the difference between the standard KZ-R3 cylinder and this Full Black prepared version ?
A: The standard cylinder retains crude foundry conduits and diagrams in accordance with standard approval. The version Full Black prepared is distinguished by its black thermal outdoor finish and a line editing work (transfers and exhaust) to maximize the filling and power perceived high speed.
Q: Does the "Full Black" treatment bring a technical advantage in addition to the style ?
A: Yes I do. Beyond the aesthetic "factory", the black coating applied on the outside of the cylinder promotes the dissipation of thermal radiation with respect to the raw aluminum, which helps to maintain a more stable operating temperature during the sleeves disputed under Strong heat.
Q: Is the cylinder delivered with the piston and the joints ?
A: No, this item includes only the full Black Full Black cylinder prepared in nicasil finish of TM Kart. The piston, the needle cage, the base / cylinder head joint pouch and the domes must be ordered separately.
