Anyone that has fooled with 4 stroke vs 2 stroke in toys knows there is a difference in power delivery, sometimes an avantage sometimes not so, everything I"ve seen in sleds so far its a disadvantage. The hicuping every once in awhile power delivery of a 4 stroke in a sled makes the track want to trench and has a tough time getting up on the snow. A blizzrd of 280 hp in the turbo 4 strokes can be a fun toy in vertical rock hard chutes but a real dissappointment in deep snow boondocking even if they made a 425 lb reasonable hp sled. The deep digging every 4th try power pulse is not user friendly when it comes loose things, swamps /loose sand/ deep gravel on my 4 stroke bikes, and loose snow is even more of a challenge for a hole digging 4 stroke.
Ohh, there's a few 4 stroke sleds I've ridden out there that certainly do not suffer from what you've mentioned above......and the only sleds I can honestly say I've seen dig themselves out of a hole while pointed uphill.
And to say that 280hp in deep fluff is a dissappointment......go pick up a copy of Boost - any of them, but I think it's the first one with Mike, Jason, Carlos playing in the bottomless fluff that they are not suited for deep snow boondocking.
I can't agree more with dirtbikes(with carbs) but the EFI these bikes are running, you do not see a hesitation or chop at all during power delivery. A few years ago I might have agreed with the statement......in the age of EFI....your arguement doesn't have a leg to stand on, sorry.
And the best ride I've ever had on a stock Nytro was a bottomless fluff day when the throttle was WFO. The weight is gone and it feels like a 2-stroke 600. Lots and lots of fun. That footy is on Sledjunkies 2.
Like I said, when it comes to bikes.....I can't agree more.....but add EFI and those problems don't exist.
