i think he is implying that we need some new blood in the sport and the mid range 500-600cc sleds at good pricing will get people into the sport. sidewinders are a good sled but the skill and price level needed are a bit high for my taste. sidewinders go for over $20,000.00 here new when buying current model year. i buy nc usually and my 16 was $16,000 when i bought it in nov of 18.

Right on 74Nitro the 998 is the best stock snowmobile engine to date. Rember the RX engine was a detuned bike engine and was not a snowmobile specific powerplant so don't play that card. The only other one in the running would be the 1100 zuk. The 1200 and 900T Ski Doo will not put up the numbers the 998 does in stock form.

Do your research on the RX1 engine. Some designs are same as R1 but it is a snowmobile engine only as was the Phazer engine. Very different. Biggest is gear Reduction. Our best hope for getting that back is if Yamaha decides to use a belt on a UTV with a high performance motor. To meet longevity it will have to be used. These motors we have now are not the high performance motors that made Yamaha a engine company. They are cost saving measures. Yes I am a realist and I know they cant afford the motors of past but its a darn shame its come to this.

Really easy I wonder what the major hold up is then.

TP, I have no idea why Doo isn't upping their game in the performance four stroke category, but to assume that they couldn't is just wrong.
Yamaha engines are very good, but no better than the likes of at about a dozen other high performance engine/powersports manufacturers.

Well who is leading in market share...when you figure that out then ask yourself... why they are leading.

All premium snow check sleds are over $20000 anyways. Meaning 850s.

Its $. Same with Yamaha. The existing motors are all a compromise because of it. Loss of a five valve head,Loss of gear reduction and the biggest is the mandate that engines must fit other units like UTV and Watercraft. If we were getting the best we would have a 4st engine where the cases were the bulkhead/frame of sled maybe even a V-four for absolute lowest cog and narrow profile. We also would have gear reduction and the motor would have a 13000 rpm redline. I agree with you Nitro. Any company can make a high performance motor and produce it in numbers to supply sled but not many companies can make $ doing it. Not sure how Japan did it in past well before CNC machines were so common place and made $ but they obviously cant do it now or they would.

From some bike store, only important thing is that it creates a close circuit once it is pushed, working in the same way as the key when you start the sled. I can try to find one shop in the NA tomorrow, now it's night in sweden.
But it is a great mod.

Cannon, I like the gear reduction also, but the 5 valve was scrapped across most of Yamaha's product line because it is inferior to the 4 valve layout.
Motogp, the highest level of performance in the world for engines of this size(1000cc), all run 4 valve layouts. Yamaha had to switch as they were getting their a$$es handed to them in the power department.

I believe 5 valve is superior in almost every way except $. It costs more. Yamaha put the $ saved toward better racers.

And still are. Of the 4 "premier" factories in motogp, they are tied with Suzuki for having the slowest bike in a staightline. I think that even the Aprilia is right there with them now.

I agree though, the 5-valve head was so 1980's technology. It was only corporate pride that forced Yamaha to keep it as long as they did.

Sure is great entertainment.
I subscribe to watch it all live.
Need some of that passion from the racing team to filter over to the sled division, haha

Well I call Bullhooy! A race bike is not a streetbike or snowmobile engine and that article is opinion. Yes I think Rossi was one of the greatest but all racers have personal preferences does not make the 4 valve superior except for him. All I know is having been in both types of motors the 5 valve has way less valvetrain losses. Higher rpm potential because of the much lighter valves and all my 5 valve motors I have owned never had valves go tight unlike these motors. They were like Jewelry. How can anyone see a 5 valve motors components and just not be amazed? Especially the bikes and quads with Titanium valves. You can push the valve in with one finger! Cam profile is way less aggressive also. Lot of 100000mi R1's around and look at the Apex motors.Whatever. Maybe I am old school. Those motors just amazed me. These 4 valves work and make power with a cheating Turbo on them but they will never be as special to me as the 5 valvers.
