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...

Transmission gear ratios 1st- 2.059 2nd- 1.545 3rd- 1.192 4th- .962 5th- .806 Transmission output reduction. 1.660 Transmission input reduction 1.864 Axle ratio 3.666

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.

I still have yet to locate my copy, but IMO you will be well served by one. Ski Doo has many various 4 stroke snowmobiles. They did use the V twin some years ago, now they use inline twins and triples... It is surprising (or maybe not) that the engineer did not discuss those clutches with...

I have to dig up my copy and check, it is not on the shelf where it should be.

A great book... http://www.aaenperformance.com/handbooks.asp

One of my largest is some of the seat designs.... specifically, the lack of proper head and neck support, though there are likely more issues with these seats. The head rests are often to low and/or poorly supported. During crashes and rollovers, it allows the head to move in, well, bad ways...

Stock, the Suzuki engine produces 177hp. Being turbo, it is easy to turn up the boost... but I'm sure there's more to it when pushing 300. The 4 stroke sled engines tend to be very reliable, even when pushing significantly higher numbers than stock. Snowmobiles can handle a lot of power as...

I'm not selling those stock parts just yet, but I'll let you know when the time comes. Here's a picture of the rear King IBP Shocks being fit. The upper rear mount had to be moved upward almost 3" to accommodate the length of the new dampers, Yamaha left plenty of room. Measurements and...

Budget and load to be towed?

Nice to see these builds still going on. :cool: If you want to add additional cooling to your belt case, let me know. There's a potentially good combination using Viking and Grizzly parts.

Nice. More pics please.

I did some research on the Can Am belts. The triangle w/ 3 stars imprinted on them is exciting to see... that is the mark of the manufacturer, Mitsuboshi, not to be confused with Mitsubishi. Mitsuboshi builds the best belts on the planet (more on that in a second) However, that doesn't mean your...

If you are allowed to share, what belt brand/part number are you running?

Yes, thanks. I utilize some of their products on various builds around here. Donaldson produces many great products, and I'm glad to see folks using these real filters that actually do what they are intended to - effectively filter air. I have a good filter test link, if you are interested (?)...

It's mostly stock... save for replacing the entire suspension. :p Congrats on finishing!

Donaldson Radial Seal?

Redline buggy with Nytro engine swap. :cool: https://www.youtube.com/watch?v=zZs6Mn7_F2A

I'm guessing it has the Suzuki turbo engine? I can see the intercooler...

While Yamaha has a very well designed and strong semi floating hub assembly (the nut on the end is an M24 x 1.5), I've seen enough of of you guys lose wheels to have me contemplate building a full floating system. A little searching turned up some appropriately sized parts, which also happen to...

The red plastic has been replaced by the SE matte black. Retail on all four pieces is a whopping $168.

I went with King's stock blue colors... there are more important places to spend money on this project.

It will have a 1049cc Nytro engine very soon.

I've got your Yamaha sport machine right here. :D

Full floater.

Nice.

Well, the stock 76hp cams from the Aprilia 850 will only set you back $184... if you ever get to that point. I'm sure there's more to the extra power than just cams... higher compression, maybe different cylinder heads, intake.

I wonder if it is the Aprilia cams? A quick search turned them up for $184 for the set. Sorry, getting ahead of things here! :D

Did you find factory cams, or is some one offering them? It appears that the Aprilia 850 SRV scooter engine may be the same? It produces 76hp in factory trim.

Great project. Have you checked into any of the other Piaggio 850 V twin engine variants for more hp goodies?

I don't have any concrete knowledge to share about future transmission tech. that will make its way into the UTVs. Only what we have been discussing... Properly designed and sized air flow w/ management. The constant tension belts with centrifugal clutch are also a good idea... the clutch just...

Perhaps a freeze plug from an engine could be found in the appropriate size?

Have a look at Honda's other products to see where the dual clutch transmission is used... then maybe we can gather some ideas on future UTV machines. 700 scooter, twin cylinder w/ 50 hp and 6 speed dual clutch... http://en.wikipedia.org/wiki/Honda_NC700D_Integra 1200 Motorcycle, V4 w/...

I'm interested in your choice of differentials. I build and deal with Toyotas much of the time, and I've been considering the smaller Toyota 6.7 inchers instead of the 7.5 for my 4WD UTV project. This choice is mainly due to weight, especially rotating. I recently found a really sweet all...

It's likely a 500cc version of the 420 Rancher, which uses a dual clutch system to shift it's 5 speeds.... just like many full sized autos. Cool stuff.

IMO, the swiss cheese housing has to go. Not only is preheated air the only source, but the air is completely unmanaged. The secondary clutch needs to become an appropriate fan and intake. It's large... and as the clutch shifts out it will move some serious air.

I used an 8" IBP that was on the shelf here for these mock up shots... Perhaps I should change the order to have the shocks done entirely in black to help with the sleeper look.
