The Wolverine will certainly be a nice platform for this swap, perhaps you can take it to the next level, going much further than I intend to. The nice thing with the Yami snow engines (as I'm sure you know) is the extremely large variety of clutch and clutch tuning options. Just about any...

Why not try to increase the power of the electric system? Perhaps the electric system from a car... there are many that could potentially work. In order to get speed on my machine, I'm using Yamaha ATV and snowmobile EPS parts... the steering will have a bit less than a 180 degree sweep. The...

Updates coming...

The King IBP is much like the Walker Evans with the needle, but has a major difference. With the King, the bypassed oil has its own secondary piston with valve stacks, which are independently tunable. Whereas the bypass on the WE is simply a bleed port that the needle slowly closes off (someone...

Here's an idea that's continues mulling around in my head, some input on it will be great. As mentioned in the first post, the Vector power steering uses the same motor/actuator assembly as the Grizzly Quad, the assist curve in the steering ECU is the only difference. If this was fit up to the...

It's still on, just slow moving due to other projects. The YXZ 1000R introduction has fanned the flames..... The YXM 1049 will live! FWIW, the Wolverine chassis is pretty much a Viking. The largest differences are the narrower body, DOHC engine, and longer rear A-arms for less scrub. The front...

Good info, thanks for posting it. The 1049 EFI Vector and Viper/Nytro long block engines are very close... the largest difference is the camshaft profile. While the Turbo kit sounds fun... dropping a normally aspirated 150hp 1049cc will be fun, too... and likely require a reprogramming of the...

Yamaha has great manuals, and the factory book should have all the specs for the transmission, and probably some good diagrams, too. The unit is beginning to look very impressive, it even appears to not only be pressure fed, but also has an oil spray bar directing lube directly onto the gears...

Oh, and by R1, I'm assuming you are referring to the YXZ 1000R? Or the engine?

Happy to help here, and thanks for the welcome. I've playing with this engine since 2005. There is no external pump in this setup. The pump is inside the engine, though relatively easily accessible by removing the oil pan. Here's the layout, which you are likely familiar with, but I'll put it...

Oh, yes, they sound good.... corner to corner, and at 100mph across a snow covered lake.

Yes please. I'll likely add one to the stable in a year or so. My early thoughts, if you want them? I believe the gear box and clutch have an oil pump and are pressure fed lube. An oil to air cooler and filter sound like a no brainer to me. The engine appears to be version of the Genesis...

I find the transmission design promising. It's separate from the engine, so not only can the lube be tailored for better clutch operation, it won't have engine contaminants nor engine HEAT, it will be far more effective. Heat is the big killer here... the clutch is likely fed lube directly from...

That engine... oh that triple engine... I've been driving various versions on the snow since 2005. Shouldn't be difficult to swap in the 1049cc Nytro engine. It'll push close to 150hp fairly easily in the sleds.
