FX Nytro Dominates Grass Drags Debut

Press Release –

At the opening weekend of the NSRA Snowmobile Grass Drag season, everyone was watching to see just how quick the all-new 2008 Yamaha FX Nytro 4-stroke snowmobile would prove to be.

Result? Very quick indeed. In fact the FX Nytro debut could not have been more impressive, with Yamaha racers dominating the Stock 600 single-pipe class with an unbelievable podium sweep over some determined competition on both Saturday and Sunday.

The Outlaw Grass Drags featured a 500-foot grass drag strip, a large crowd of spectators, two complete rounds of racing – and delightful Minnesota weather. Jim Jones, racing for Hauck Powersports, started up Saturday’s action by winning Stock 600 Single Pipe over Allen Ulmer (Ulmer Racing) and Jerry Fix (Fix Powersports) in a historic 1-2-3 sweep for the new FX Nytro.

Sunday’s round-two action proved a virtual repeat as Jones led a 1-2-3-4 Yamaha sweep in Stock 600 Single Pipe ahead of Ulmer, Fix and Hauck, all aboard ’08 FX Nytros.

“All of the races were close – they could have gone either way,” Jones said afterwards. “I have to credit my boss, Pat Hauck, who does a great job setting up the sleds. But I was also impressed by the FX Nytro power. It pulls off the line strong, went fast and was easy to ride.”

Which 4 Stroke For The Trails?

Q: I am having a tough time deciding detween the Apex LTX / Attack with the Gen150 engine and the new Vector LTX models with the Gen120 carbed engine in the Deltabox II chassis.

A: The 120 HP Vector powered Apex chassis handles noticeably better than the 150 HP four cylinder. It’s all about weight and you can feel it. Inside ski lift is decreased in the 120 and an over-all more “flickable” feel accompanies the lighter engine.

Q: Which do you think is the better choice for trail riding in the 60-90mph range? I ride pretty fast but seldom push past the 100mph mark. I also enjoy comfort more than crushing the bumps so I don’t need a sled with a rough trail calibration, that is why I am leaning towards the LTX models with the monoshock rear.

A: Sixty to ninety MPH? That’s moving Bud! I think you better go for the Apex 150 – if you’re running at the high end of the speedo you’ll be stretching the rods on the 120. However, if you’re riding in the 50-80 MPH range, the 120 HP engine will keep you happy.

The LTX with the running board klicker adjustment for the rear mono-shock is an excellent choice for all kinds of serious trail honing. The good news is you can dial in enough compression damping to fight-off a sno-X course – if you desire.

The adjustability here and in particular the inherent plushness of this skid and damper is pretty much without equal in the biz right now. Oh, one more thing – the Vector motor in the old chassis (we haven’t had enough time at sea-level to verify MPG on the new chassis) was a virtual tie for the best MPG numbers we recorded last year on a full-build production snowmobile.

The Apex 150 four cylinder is not as miserly as the 120 Vector mill. More horses require more hay.

Q: After coming off of a 1998 ZR with a 135hp D&D 711cc big bore engine, do you think I would be satisfied with the power of the Gen120?

A: You’re not serious asking this – right? No, you won’t be satisfied. You better get an Apex 150 and save yourself a lot of frustration.

Yamaha lists both the Apex LTX and Vector LTX as the same weight, 577lbs.

Something’s wrong there.  We’ll check into this.

Thanks for your replies Mark, your input is much appreciated!

You got me thinking….when my ZR6 was stock with about 100hp on tap, it was actually quite fast enought for me.  I do ride fast, but only when conditions allow me to do so (the long railroad grades in the Upper Peninsula for example) and then I will sometimes see 90+ mph on the speedo.  My average speedo reading in good conditions is more like 70mph, maybe a bit more or less. 

Actually, I don’t think my 711 is much faster on top end than my 600 was.  It pulls much better down low and in the mid range but top end is maybe 110mph speedo indicated (probably more like 100mph gps).   

I honestly think I will be satisfied with the torque and pull of the Vector 120 engine.  Most people say that is is about equal to the Apex until around the 80mph mark and I think, choosing between the two, I would rather have the lighter steering and weight over the 30hp. 

The ultimate engine in this chassis would probably be the EFI G130 found in the Nytro, but for now all we have to choose from is the 150 and the 120. 

The only sled that left me wanting more was a Z570 rental that I had a few years back, it was about 10mph too slow for me (could just about hit 75 mph on a very long, straight and flat trail).  I had the throttle duct-taped to the bar for 300 miles through the UP.

Reply:

Sounds like you know what you want. You’ll be happy with either as they are both exceptional sleds. The Vector will stay with an Apex to about 50 MPH (80 klicks) not 80 MPH. However at trail speed I believe the new Vector would out-handle the Apex – hands down. There’s that much difference.

Global Warming a Hoax?

An amateur meteorologist from Toronto has embarrassed NASA scientists by catching an error in recent climate-change data. The resulting flap has led to accusations and finger-pointing over whether NASA’s error was genuine.

CBC News
Thanks to blogger Stephen McIntyre’s calculations, climatologists at NASA’s Goddard Institute of Space Science (GISS) in New York now concede that 1934 was the hottest year in U.S. history, and not 1998 as it previously reported.

McIntyre first emailed NASA on Aug. 4 saying he’d discovered an error in its climate change data from 1999-onwards. He noticed inexplicable jumps in temperature around that time and, as it turns out, NASA’s temperature readings have all been too high since then, to a maximum of 0.15 C.

NASA has since adjusted its numbers. They now show that 1998 is the U.S.’s second-hottest year and that five of the 10 warmest years on record in the U.S. date from before 1939. The worldwide numbers remain unchanged, with 1998 and 2005 tied as the hottest year on record.

McIntyre’s findings did more than just embarrass NASA, though. They have triggered a storm of criticism from climate-change skeptics who accuse NASA of inflating the numbers to promote global hysteria over the environment and others accusing NASA of trying to keep the error quiet.

Meanwhile, climatologists at GISS say their critics are making a mountain out of a molehill and that the differences in the recalculated temperatures are so insignificant that they have no impact on the overall trend towards global warming.

They attributed the error to a new data collection system established in 2000 that used different methods than the previous one.

Suggestions For an ’04 500 SS

Question:

I have an ’04 500 SS and love everything about the sled except the milder 600 engine. Where I ride it is all open truck trails and we speed along at above 75 mph.

I was wondering if you knew of any big-bore kits for this sled or performance kits I could put on my sled?

Mark

Response:

Thanks for your email!

My most serious suggestion this week is for you and this question. I would recommend you not do anything to your SS other than work a trade deal on a new sled.

Honestly, anything you’re going to do to get the kind of power you are looking for would be better answered with a move to a full-on 120 HP SDI 600 Rev. I understand there are some non-current 07’s which may be available at attractive prices.

Compare what the cost of trading up would be versus serious HP mods – this will include the improvement in resale you’ll experience from trading up versus no possible recovery of the extra dollars you might invest in hop-ups.

Good luck!

100 MPH AND CELEBS I KNOW

Winter in Toronto. Still wicked cold and take your breath away morning air. Old buddy, Kent, showed up in a brand new Dodge truck with a hemi. It was red. And, it had an ipod, xradio and leather. Sweet.

As I climbed in I thought of the ’82 three-quarter ton, standard cab, long box that I had torn apart in the shop at home. The old 318 with a torque-flite would suffice, but the hemi was, well, a hemi.

East, down the 401 then north and into Minden. Blue sky, bright sun, but still cold. Reached for my prescription sun-glasses and just when I needed them most, busted right at the bridge. Squint and bear it became my motto. It was worth it. The scenery was spectacular and the colder air held the landscape as a winter wonderland.

Try these on. Boots, gloves, helmet and insulated suit felt pretty good. The embroidery said, “SUPERTRAX” and the colors said “wow!” What’s better than yellow and red and black? Everything felt professional and competent. I was, like, on the team and belonged. If only my name had been done in script over my chest.

Outside, brother Mark, was fueling and documenting the inventory. “ Need a piece on that one and the widget broke on the new red sled. You ride those. I ‘ll ride this. Let’s do it!” Over the drift, down the path and onto the lake. Pristine, bright, frozen, fabulous.
I looked down and saw gauges and switches and rockers and handlebars. Heated bars? Alright! Moments later in the middle of the frozen lake I was looking for the heat adjustment on the bars but discovered how hard it is to figure it out when you’re running eighty.

But eighty it was and as I looked left and right there were the Lesters in the Sunday afternoon sun with powdered snow blowing off their sleds and not a care in the world. Eighty felt so good I squeezed to push the needle to eighty-five. Wow, eighty-five on a snowmobile! Ninetys got to be close. But, eighty-nine was as close as I could get. Still, one mph below ninety on a sled is movin’! At least for me.

Several lakes later we pulled in for a burger. Unzip, unsnap, undo, undress. Inside the lodge we found a table by the window and the SUPERTRAX gear was strewn over the chairs and empty table top. We ate, laughed, reminisced, joked and talked about old times. Paid the bill, pulled on our gear and headed back outside.

There was a young girl, maybe eight, and her Dad standing by the sleds. “You guys testing today?” took me by surprise. “Huh?” was the best I could do. “Saw you in the restaurant and I told my daughter it was the Lester brothers from SUPERTRAX. See it is them. It is the Lester brothers” It then dawned on me. It was the Lester brothers! My old buddies from childhood were now celebs. Very cool!

“SUPERTRAX is the best snowmobile magazine out there” he continued, “never miss an issue. We drove up for the long week-end but never dreamed we’d see Kent and Mark Lester.” I kind of wondered if the paparazzi were close by.

Next morning after a ride through the trees and trails, I mentioned to Kent that one day I’d love to see 100 mph on a snowmobile.

Big smile and a twinkle in his eye told me something was up. Behind the lift up door was yellow and black magic begging to be ridden hard. “One hundred and fifty horsepower, dude! No problem doing 100. Take it out!” Didn’t know it was a prototype but when I squeezed the throttle, the front end came off the ground and my heart jumped into my throat.

Everything was a blur and when I looked down I saw one- sixty on the speedo. Doing the math conversion from kilos to miles per hour at speed caused my eights and fives to jumble together but I thought I was close.

And, close I was. In fact when my helmet came off , all that was left was a grin. Oh, yeah! Adrenalin, testosterone, gas, oil and nervous sweat all mixed together in one glorious elixir . Oh my. Addiction never felt so good!

After my connecting flight in Chicago, I looked into the black of the night sky and thought back. What an incredible experience.

One hundred miles an hour on a snowmobile, good life-long friends who are now celebrities, the wonder in a little girl’s face, post-card scenery, hundreds of miles of trails and lakes to ride and the really cool, yellow, red and black SUPERTRAX gear. Now, if I could just get my name embroidered on the chest.

SUPERTRAX International staffers are gearing up for a busy Fall Snow-Show Season beginning with the hugely popular Sno-Barons Hay Days event the weekend after Labor Day in Forest Lake just outside Minneapolis, Minnesota.

The SUPERTRAX Crew will be on hand meeting readers, telling ridiculous and mostly unbelievable snowmobile stories and generally carrying on with the huge crowds always in attendance. Mark your calendar now for September 8th and 9th 2007.

The SUPERTRAX International Crew will criss-cross the US/Canada border the last weekend of September 2007 – namely the 28th thru the 30th and attend the Ontario Federation of Snowmobile Club’s (OFSC) first ever Go Snowmobiling Show held at the Toronto Congress Centre near Pearson International Airport in Toronto.

The brand new Go Snowmobiling Show will see the return of a fully OEM supported, glitzy show for the first time in five years in the Toronto and Ontario Marketplace.

We’ll be on hand with a great display, mags, special subscription offers and more opinions on what the new iron – all of which will be on display – will run and ride like. Link to the Go Snowmobiling Show right from our site.

Next stop will be the Snowmobile USA Show in Novi, Michigan. This is one of our annual favorite events because the attendance is huge, the show is huge and it happens so close to the real season – the weekend of Novi 2nd, 3rd , 4th 2007.

We’re on hand to answer your questions, give out free stuff, get you a subscription at a Show Special price and generally be in your face all three days.

The Novi Show draws snowmobilers from across the Eastern US – even as far as Maine! Many Canadians visited our booth last year looking for great deals on stuff at the show. Don’t miss this one – we won’t!

How Much Torque for The 4-Strokes?

Question:

Hello,

I wanna know how much torque the Yamaha Apex, and Yamaha Attack have.

You all always talk about how much torque is in the four strokes, but never put a number down that I’ve seen. How about the Polaris classic turbo also?

Thanks, from a guy who has nver ridden a four stroke sled.

Tim

Response:

Excellent question, Tim.

We have had difficulty getting the torque numbers for 4-strokes, too. The OEMs are a bit reluctant to give them because the impression of a 4-stroke is that it generates way more torque than a 2-stroke.

At the end of the day the numbers are actually quite similar, but here’s where the difference lies.

Take for example a 1000cc 2-stroke: We know that Cat’s 1000 makes a claimed 120ft-lbs. Although we don’t have the numbers for a Yamaha’s 1000 4-stroke Apex we suspect the actual torque peak is somewhere close, perhaps even less.

The difference is where the peak torque comes in on the RPM scale. 4-strokes tend to make the highest percentage of their torque at lower RPM than 2-strokes.

For instance, although a 1000 Cat may produce 120 ft-lbs, it may not show up until 7500 RPM. The 4-stroke may make 110 ft-lbs but it peaks at a lower 4500 RPM. This gives the impression of a way torquier power delivery, even though the peak number may be lower.

If you’ve spent any time with a 4-stroke you know those engines have a feeling of disproportionate grunt down low but sign off quicker than a 2-stroke.

The other difference is that the torque curve on a 4-stroke is flatter, perhaps reaching its peak at 4500 and maintaining over 100 ft lbs up to 8500. 2-strokes tend to need more RPM to generate a more peaky torque curve that may be over 100 ft-lbs for a narrower span – say, 6000 to 8000 (I’m just guessing at these numbers, but you get my drift).

Turbo 4-strokes are similar. Always remember, a turbocharger is a torque generating device. It makes the engine think it’s bigger than it actually is. If the boost is set for low RPM, you’ll get a huge increase in torque at a lower point in the power scale.

Depending on how they’re set up (say if the boost continues beyond the peak horsepower point), you’ll be building torque all the way. You get that feeling of enormous grunt from boost until sign-off – one of the reasons I, personally, love turbochargers.

We’ll try to get some actual numbers for next season – hasn’t been easy so far.
