Wie der M3X wurde auch der M3X V2.0 speziell f\u00fcr maximale Leistung und Abstimmbarkeit entwickelt. Mit diesem Motor haben Sie eine gro\u00dfartige und super gleichm\u00e4\u00dfige lineare Leistung von niedriger bis hoher Drehzahl.<\/p>\n
Vergaser, Kurbelgeh\u00e4use und Kurbelwelle wurden entwickelt, um den Kraftstoffverbrauch zu verbessern.<\/p>\n
Englische Version<\/h6>\n
This is the 3 port .21 Off-Road Ultimate M3X V2.0 Ceramic Competition Engine. Like its predecessor M3X, the V2.0 is made by the prestigious Japanese O.S. Engines brand and it’s based on their square stroke Speed B21 Ty Tessmann II edition engine.<\/p>\n
Like the M3X, the M3X V2.0 it\u2019s been specifically designed for maximum power, performance and tuneability. With this engine you will have a great and super smooth linear power from low to high R.P.M.<\/p>\n
The carburettor, crankcase and crankshaft have been developed to improve fuel consumption.<\/p>\n
COOLING HEAD<\/p>\n
The cooling head has been redesigned by Modelix. It\u2019s not as low as the B2102 lower profile but it\u2019s lighter so it keeps the centre of gravity as low as the B2102 but improving its performance on very high temperatures. It\u2019s the same head as the M3T and M3S engines.<\/p>\n
CARBURETOR<\/p>\n
Unlike the previous M3X, the V2.0 comes with the 21 J3 carburettor. Its high-speed needle holder has been redesigned for a better refrigeration of the fuel flow into the carburettor, lowering the temp of the carb, and consequently it\u2019s more stable with a great idle stability, improves fuel mileage and overall engine performance.<\/p>\n
Besides this, the uniball joint of the carb slide has also been modified with two stoppers instead of one. With this new modified design, you can easier adjust the angle of the uniball joint without having to disassemble the engine.<\/p>\n
This carb offers a higher accuracy tuning, a very interesting advantage to experienced drivers.<\/p>\n
BACKPLATE<\/p>\n
The original design of the OS backplate has been modified. It\u2019s been milled to improve the gas flow going to the piston.<\/p>\n
The backplate is CNC machined and made of 7075-T6 Swiss Aluminum. The reason of making it with this material is to make it harder than the original and reduce the conrod-backplate friction increasing the life of the conrod and improving engine efficiency and performance.<\/p>\n
Thanks to its design, you can remove the backplate without damaging the conrod even when it is on its lower position (PMI). The lateral grooves\u00a0allow to easily remove the backplate without having to use any tool that can damage it.<\/p>\n
CRANKSHAFT<\/p>\n
The crankshaft selected for this V2.0 version is the B2101 one to increase the power at low RPM. This crankshaft has been designed by the O.S team of engineers to ensure an optimum flow of fuel thanks to the aerodynamic design and the silicone filling. It is balanced with a tungsten weight in order to increase the inertia to rotation.<\/p>\n
BEARINGS<\/p>\n
In line with the high quality and performance of this engine, its two high precision made in Japan bearings ensure high idle stability, longer life and low friction at high temperatures. Ceramic bearing in the rear and steel in the front.<\/p>\n
VENTURIS<\/p>\n
The engine is supplied with a 6.5mm aluminium venturi.<\/p>\n
SLEEVE AND PISTON<\/p>\n
The sleeve with 3 inlet port and an exhaust port guarantee a low fuel consumption with a very high but smooth and linear power.<\/p>\n
Both, the sleeve and piston are made from a high strength aluminium bar to improve its durability.<\/p>\n
