Eventually, the know-how gained in the development of this engine would form the base for subsequent development of the 3-cylinder and 2-cylinder snowmobile engines. Yamaha 4-Stroke Snowmobiles 10th Anniversary Site, Pioneering: The Aim of the Shift to 4-Strokes, Distinct: The Character of Yamaha Engines. Peak horsepower figures were 138.6 HP on the FX Nytro and 122.6 HP RS Vector. The engine it employed was the 998cc liquid-cooled 4-stroke, DOHC, in-line 4-cylinder, 5-valve mill developed specifically for that project. Mohawk Aero provides parts, help, and complete kits to convert Yamaha 4-stroke, water-cooled 120-150 HP snowmobile engines for use on propeller-driven air boats, hovercraft, gyrocopters, helicopters & fixed-wing aircraft. Redesigned specifically for snowmobiles, it took form as a 973cc liquid-cooled, 4-stroke, DOHC, 4-valve engine with an in-line 3-cylinder layout. Revisions in the intake/exhaust systems, addition of fuel injection, changes in the crank web (-770 g) to optimize crankshaft inertial mass and other measures produced a dramatic improvement in response. In profile, Yamaha's 2-cylinder snowmobile power unit was a 500cc liquid-cooled, 4-stroke, DOHC, parallel 2-cylinder, 5-valve engine. The development targets for this new Yamaha engine were: "super lightweight, super compact and high power output." This year, you can find two performance WaveRunners in Yamaha’s fleet.. Little did we know it would become one of the most popular snowmobile 4-strokes of all time. Though she is old, I love her rough feeling. Yamaha engineers have also developed designs to reduce pumping loss by means of dry sump systems in the 2-cylinder and 3-cylinder engines of its snowmobiles. Dealer Products Menu. The concept was a snowmobile for X-treme sports. The key to this new dimension of performance was the 2-cylinder engine. Without it, your vehicle will not operate, and your valued means of transportation will be useless. Employing the concept of a "snocross racer replica," the first 3-cylinder engine model was developed in a project that included participation in Snocross races in North America and Japan to achieve cutting edge performance and weight reduction to racer levels. This helps improve engine reliability. It’s true, and may be one of the industry’s best reasons for 2-stroke lovers to convert to a 4-stroke.

Code: 1WG . Another factor in this was the specially designed crankshaft. Accessories & Apparel. Compared to the YZF-R1 engine which had the same displacement per cylinder, this connecting rod was 3 mm shorter at 100 mm, which reduced the weight by 25 g. Normally, for the ratio between the connecting rod and the radius of the crankshaft—know as the lambda—a ratio of 4 : 1 is considered standard, but the lambda ratio for this engine was 3.7 : 1. In contrast, the crankcase, cylinder head, lubrication system (dry sump type adopted), cooling system, reduction (gear) shaft and other parts were redesigned specifically for the RX-1. Instead of a gear reduction system, as found on some four-stroke designs, both versions of the Genesis 1049 engine has a primary clutch mounted directly to the crankshaft. During this time it has rightfully gained … The exhaust layout was changed from 4-2-1 to a new 4-1 design and the Exhaust Ultimate Power Valve (EXUP) system was adopted for the first time ever on a Yamaha snowmobile. After the 285 grew long-in-the-tooth, a 301cc was built on the same design platform, but it pumped out 9.5hp. Why the change of heart? Yamaha Vmax Engine Specifications. Its base engine was none other than the epoch-making power unit of the original supersport motorcycle, the YZF-R1. The engine would later undergo further development and evolution on the FXNytro and became a motor of choice, capable of serving in a number of areas as an important pillar of Yamaha's 4-stroke performance. As designers began to appreciate the benefits of multi-valve layout, 4-valves-per-cylinder (and even 3-valves) became common.

Complete Specs Here By shortening the connecting rod, the engine could be designed with less overall height, and by calculating in effects like that of a wider cam pitch, the distance between the crankshaft and cam shaft axis was reduced by slightly over 10 mm compared to that of the YZF-R1 at the time. Long hours of development work were also spent finding the optimum exhaust system settings for this design. In a multivalve engine, maximum rpm is limited by the size of the largest valves: in a 3-valver, the exh… Not long ago, Yamaha’s stance was that if it wanted a 200 hp snowmobile engine, it would build one without needing to rely on turbo. Efforts like this helped make the 3-cylinder engine outstanding in the kind of all-around "total performance" Yamaha engineering always strives for. The G2-G9 models had a Yamaha-built 4-stroke 285cc 8.5hp, single cylinder engine. At 160 pounds, the TR-1 HO weighs about 30 pounds less than the MR-1.

However as a 4-stroke snowmobile engine, it would be newly designed in basic dimensions such as the overall height of the cylinder head and connecting rod length. These changes brought a reduction in engine height of approximately 30 mm compared to the YZF-R1 engine. To produce higher power output, fuel injection was adopted and, with consideration for the fact that maximum power output would be reached at 11,250 rpm, a crank phase of 180 degrees was chosen to enable the use of a single-shaft, coupled-force balancer and thus contribute to a more compact engine design.
