Welcome to my build-up of a 2014 Yamaha Viking. I purchased the unit new last fall, and covered a whopping 21 miles before placing it in the garage for the winter snowmobile season. For those unfamiliar, the stock 686cc thumper is a lightly warmed over Rhino/Grizzly engine, and it produces a tad under 50hp. The chassis is an excellent mid-wheelbase unit that is begging for more power and suspension. I heavily considered building the 686 using an Aisin AMR 500 Roots Supercharger, titanium intake and stainless exhaust valves, etc etc. After riding my Yamaha Nytro this winter, I knew the 686 would have to go, and a Yamaha 1049cc triple would be the power plant of choice.
Last week I found a 2013 Yamaha Vector Snowmobile being parted out. The Vector uses a very slightly detuned Nytro engine, it has different cams than the Nytro, but essentially everything else is the same. It looses 5 hp up top, 130 vs 135, and likely has a fatter torque curve in the low and mid, which is beneficial for a side x side.
The transmission to be used is a Yamaha VK Pro/Viking Snowmobile H/L/R unit, and the whole assembly will mount longitudinally.
Another really excellent thing about the Vector, is that it comes with electric power steering just like the ATV and UTV models. The wire harness and PS parts are all coming with the engine, and I suspect that I will able to integrate this into the Viking. The Vector and Grizzly and actually share some power steering parts, the drive motor being the most notable, and have the same harness plug ins. I'm hopeful whatever combo of parts I end up using will be able to communicate with the Vector ecu and make for a very tidy and capable install.
The suspension for this season will likely use stock arms and of course use Ohlins Shocks, since I work heavily with them for many custom applications. Travel will be an adequate 12", but the tuning will make it be able to run in larger company. The Ohlins Shocks I frequently use have the PDS/Progressive Damping System, which is similar to, and predates by many years, the Fox BOC system.
I'll add pictures and info as it becomes available or requested. Questions, comments, and criticisms welcome.
