What will you be riding now? Why ya sell that machine? all tricked out and ready for action. Heck the motor was just getting broken in.

YXZ smokes CVT clutched machines of the same horsepower, more efficient. Heavier with a CVT and less horsepower..... doubt it would be much of a race.

Yea it’s magic! FYI a V-4 with the modified uneven firing order makes less horsepower than an even firing order. Basically increased torque with a compromise of lower horsepower.

Back when I first owned my 2015 Viper I talked to other owners of Vipers and many times they had no idea the Chassis was made by Arctic Cat. Perhaps things have changed. Yamaha is known as a Motor company, many will assume it has a Yamaha engine, along with Yamaha’s legendary reliability. Why...

:crap:

They know your average Joe has no clue, thinks he’s getting a Yamaha. Just running the name into the ground for profit.

This was pulled from the article I posted.... “There are also pumping losses, which is the power wasted in pumping air through the engine from intake to exhaust. Up to 300 litres of air per second flows through a 1000cc engine at 18,000rpm, and a V4 crankcase layout deals with that flow much...

I’m not so sure that crankshaft vibrations can cause valve train issues....but I am positive that the springless mechanical valve actuation used by Ducati will allow a much more aggressive camshaft profile and ultra high rpm without valve float...

https://www.motorsportmagazine.com/articles/motorcycles/motogp/why-are-motogp-v4s-faster-than-inline-4s Interesting, not a lot of details tho. The inline bikes have two extra main bearings, so a tad more parasitic drag but capable of more horsepower when power adders are used. I can see less...

Not a one of those MotoGP bikes could hang with this bike as far as outright power and speed..... The fact that it’s a V-block design has nothing to do with horsepower of the engine. Like I said inline motors have always inherently by design, been able to hold more power than V-block motors...

Yamaha and Suzuki both still use an inline 4 cylinder. The biggest reason for using the V4 is its width, much narrower, great for a sled application IMO. Olav Aaen had a prototype 2 stroker back in the day, wish I could have actually seen it in person. Technically the inline motors are...

What’s the estimated horsepower on that beast?

STEeeeevOooooo! I knew that wouldn’t last long! (my voodoo SkiDoo sled worked!) $hit was getting pretty gloomy around here, now we can get back 2 laughing and loving! Glad your back! None of those, White Zombie.....La Sexorcisto 4 me You can “Doo” Mary Ann while I give it 2 Ginger in the A$$! :D

details? What car? What turbo? Road tuning?

FIII will smoke a 670 rotax, been there, done that. My buddy had the 97’ formula with that ExpertX style suspension.......when we traded sleds, he wouldn’t give mine back! She’s still running like a top with 18k miles. Still have my “Free” Leather when I bought the sled too! Updated...

oh come on you guys, that’s hilarious ^^^^^^^^

And much cheaper to build, one less of everything needed to for an internal combustion engine. I’m sure they will pass the savings on to you. Industry has been pushing less cylinders in their engines for years now, claiming the “more torque” card. More torque is easily achieved through...

Yes, the 998’s are stronger than the apex blocks believe it or not. Rods, pistons and valve springs is all that’s needed for 500hp without issues......now that’s insane.
