Mileage on Yamaha 4-strokes

Question:

I had an ’05 vector and currently have an ’06 Rage and a ’07 Attack. I have never exceeded 15-16 mpg with the first two and have not bettered 13-14 with the Apex.

Are you running the machines at 30-40 mph? What gives?

Also, have any of you ever changed the oil filter on a new Apex? As much as I love the 4 stroke yamaha’s, the Apex oil filter change is ridiculous.

Sincerely,

R. Witte

Thanks for your email!

The oil filter ritual on most 4-stroke snowmobiles can be a challenge. You need to think about how many times during the riding season you didn’t have to saddle bag oil bottles, fill up an oil tank daily (nightly?) or buy injector oil by the case when you are struggling with the once a year oil filter change.

I’m not trying to be smart, but here’s where the rubber hits the road – new 4 stroke sleds are tightly packaged and because snowmobiles need a completely enclosed belly we are limited in access to the engine area. It’s the nature of our machines.

The fuel economy issue is intriguing. We ride our sleds hard and fast – honest. In fact we have some of North America’s best lake running at our Canadian facility located in Central Ontario.

We run lakes at WOT all the time. Not good for mileage. Having said this – we have already seen 20 mpg (US gallon) from our Attak GT. Go figure. This sled has almost 2000 miles on it today.

In the past we have recorded over 21 mpg with a Vector/Nytro. We are not using factory tweaked units but real, full-on production sleds. Trails at high speed and lakes at WOT.

This season it has been difficult to get big numbers because we’ve been riding on what amounts to unpacked snow (no hard base) all season. We are having our first mild spell since the snow came.

With unpacked snow on trails skis tend to “sink” and generate much more parasitic drag than running on harder snow. When we’ve run on hard pack, we get better mileage – I would guesstimate as much as 20% better. When it’s loose and cold, we get less mpg on everything.

Hope this helps,

FIRST IMPRESSIONS: Arctic Cat F-8 Sno-Pro

Here’s a light rundown of our impressions on the 2007 sleds we’ve been racking miles on this winter.

We’re still trying to figure out our F-8 Sno-Pro. The Sno-Pro name has always been closely linked to snocross and ditch banging but we’re struggling to make that connection.

The adjustable seat and handlebar lets us find the perfect fit for every rider, every time. Its weight does not defy gravity and although the 800 mill is very sophisticated, it doesn’t produce over-achieving power in this chassis.

Fox Floats look mint up front and more importantly, inspire confidence when running hard in all kinds of trail conditions.

The overall appearance is clean and smooth with an aura of quality not seen on previous Cats and we love the jumbo-size storage out back.

Electric reverse is flawless but we find the button hard to operate with gloves on.

HOLESHOT: REV XP Platform Making Its Mark

By: AJ Lester

Seems Ski-Doo sponsored teams in the WPSA lucky enough to have the ultra light XP chassis are enjoying the new REV platform. Supertrax was on site at the WPSA Grand Prix event in Valcourt, QC Canada and witnessed the XP being put to the test.

From the moment it hit the track, racers were loving the light weight and more centralized design of the XP chassis throwing down impressive track times and whipping the XP like it was a freestyle competition.

The Crew here at Supertrax has racked up some serious miles in the short time we’ve had our ‘08 XP 800R Adrenaline. The new motor is a force to be reckoned with pulling hard from initial tip.

It leaves our 2007 XRS 800 in the dust and it’s no slouch! The 800R seems to just sip fuel, matching and sometimes bettering our 600 SDI Ski-Doo at the pumps.

Handling and ergo’s are far superior to the original REV and actually make it seem old fashioned when switching back and forth. Knee angles are improved allowing riders that complained of sore knees on the original REV to ride comfortably.

Cheese grater running boards scream lightweight and do an amazing job of clearing out the snow even in the deepest powder and the huge weight reduction is noticeable on the trails allowing the rider to push the sled around when carving a fast line.

Grab the latest issue of SUPERTRAX for a closer look at the new 2008 Ski-Doos.

Cat’s Simons Earns First Pro Victory

Press Release –

In his first two seasons as a full Pro-class rider, Ryan Simons showed flashes of brilliance but sometimes struggled to put whole races together. It’s safe to say those troubles are long gone.

Simons – already enjoying a breakout season on the World PowerSports Association (WPSA) National series – had the best weekend of his short career at the Eagle River, WI, double National February 23-25.

Simons scored his first-ever National victory in Saturday’s Pro Open race and he came back to take third in Sunday’s Open contest. The 24-year-old now has five podiums on the season in addition to his Winter X silver medal and sits in second in Pro Open points. “I was pretty pumped up to get that win done,” Simons said. “I just tried to stay calm and treat it like a heat race.”

The win certainly didn’t surprise Arctic Cat Race Manager Russ Ebert. “Ryan’s been riding great all year and this was just a matter of time,” Ebert said. “And I attribute at least part of that success to the chemistry on his HJ Racing team. Ryan is very hands on, understands his machine, knows what he wants from his suspension and provides excellent feedback. It helps that Hector [Olson] and Corey [Berberich] are two of the best; they’ve helped several riders get their first win.”

“The whole team is great,” Simons said. “Corey and Hector are good at what they do and our maintenance program is fantastic. Everything is so fresh each weekend and they do whatever it takes for us.”

Simons wasn’t the only member of Team Green to perform well at Eagle River. Despite being plagued with a draining flu, Carl Schubitzke – fresh off his first National podium of the season the week prior at Valcourt, Quebec – notched three top seven finishes and made all four of the weekend’s finals.

Arctic Cat drivers dominated several of the support classes, just as they’ve done all year. Cat’s stable of young future stars combined to collect half the podiums in both the Semi-Pro and Sport divisions.

Besides procuring a pair of podiums, Dan Ebert now leads both Semi-Pro points chases. Dusty Miller had two Sport-class top-threes, and Kyle Pallin chipped in with both a Sport Stock podium and a Junior 16-17 victory. Cody Thomsen added a win in Junior 14-15.

“Cody is a neighbor of ours from Nisswa and an excellent motocross racer,” Ebert said. “We’ve got a great crop of talented Junior drivers and he’s one of them. It’s exciting for me because they’re the future of racing, and they’re all fun to watch.”

Just like the rest of Team Green.

Cat’s Davis and Palin Cruise to Iron Dog Title

Press Release –

The Tesoro Iron Dog is the most daunting cross-country snowmobile race in the world. Covering 2,000 rugged miles through some of Alaska’s most trying territory, the Iron Dog might just be the biggest test a snowmobile can face. Little wonder that Arctic Cat-mounted competitors have captured eight of the last 10 Iron Dog titles.

In 2007, the Arctic Cat duo of Scott Davis and Todd Palin earned the win. Riding a new F6, the pair finished the grueling seven day race in 38 hours, 7 minutes and 7 seconds, nearly 50 minutes better than the second place squad. It was Palin’s fourth Iron Dog victory, with the most recent three all coming on Cat.

Davis collected his seventh Iron Dog title and fifth on Cat. At 47 years old, Davis is the oldest person to win the event, and he and Palin avenge last year’s bitter defeat, when the team lost by a single second in the closest Iron Dog finish ever.

“This win is the most satisfying that I’ve had, especially at my age and after what happened last year,” Davis said. “There are so many things that go in to winning this race: You have to have a great partner, a good team and a snowmobile you trust, and then all you have to do is go 2,000 miles without screwing up.”

Palin and Davis certainly found a trustworthy sled – they chose the all-new F6. “We were a little nervous about it at first because it’s a new chassis,” Davis explained. “But once we began testing we knew we wanted to use it. The ride is superior and takes so little effort. You can ride for 300 miles and not even feel it; there’s much less fatigue. I’m 47, and I was able to go hard because the ride’s so comfortable.”

“You’re riding further forward on the machine [6 inches further forward compared to a Firecat] and it’s so smooth; we felt like we had the best-riding sleds in the race,” he continued. “In terms of terrain, this was the toughest Iron Dog in years: We had rock hard snow, frozen tundra and exposed obstacles. It was a real test for snowmobiles, and the F6 passed with flying colors. The durability was great, the front end works fantastic and the chassis didn’t flex. In those conditions, you learn a lot about your sled in a hurry, and I was very impressed.”

The Iron Dog has long been a proving ground for new Arctic Cat platforms; Team Green’s first victory in the contest came in 1993 – the debut year for the legendary ZR chassis. Cat has dominated the event ever since.

“I think the Iron Dog is an excellent example of our engineering division’s commitment to quality and durability,” Arctic Cat Race Team Manager Russ Ebert said. “We take great pride in building bulletproof snowmobiles, and the results of our work are obvious in that race.”

Switchback Fuel Consumption Issues

Question:

There are a lot of 600 CFI owners concerned about the lousy gas milage and low oil usage and I’m one of them, however the three dealers I’ve talked to are not concerned even though I just gave them a lot of money!

My sled gets 10 MPG most of the time and I see 11 MPG once in my 960 miles. My buddies with SDI and even 600 carbed are laughing at the milage!

I would like to see at least around 15 MPG for the trail cruising I do. I understand a 144″ track will take more gas but my old XLT , which weights a little more, get’s the same milage as this new “high-tech” CFI 600. Also this sled consistanly uses 1 oz of oil to 1 gallon of gas. I

I’ve heard rave reviews for this sled but now wondering if it really was the same sled. Have you heard anything on your end about the poor milage or low oil consumption?

Thanks,

Steve

Response:

Just finished a 185 mile day with 8 of our PR sleds. Did mileage comparisons on all. We ran a mixture of lakes at WOT and trails at brisk speeds – not good for mileage.

The lowest we saw from the 600 CFI was just under 12 mpg – but in comparison to everything else we had along – including the remarkable SDI 600 Ski-Doo – the mileage was not out of sync from a comparison standpoint.

We have seen as high as 16 mpg out of the IQ 6 CFI this season. The sled has almost 1500 miles on it today. The oil consumption on our 600 CFI is scary – but the engine runs sweet, is fast and I personally had the privlege of holding it wide open all the way up the infamous Kevlar Lake (the Bermuda Triangle of snowmobiling) here in Central Ontario – yesterday.

I do not find the economy we’ve experienced to be bad – keep in mind, this season – thus far – has presented poor conditions for fuel economy – the snow has no base – is mostly loose all the time and the sled tends to sink into it creating extra parasitic drag from both the track and skis. We find hard-pack conditions influence economy by 15-20%.

Thanks,

Motorhead Mark

MARTIN WINS FOR WISCONSIN AT EAGLE RIVER

Press Release –

It took him nearly two months, and several near misses, but Wisconsin’s Ross Martin finally brought the winner’s trophy home with his victory in the Pro Open final Sunday at the AMSOIL Eagle River Derby Track. The event was part of the second round of the WPSA PowerSports Snowmobile Tour’s Eagle River Snocross National.

Martin (No. 837 Judnick Motorsports/Polaris), who took the top qualifying spot, fought off early pressure from Levi LaVallee to take the victory, his first since sweeping the Duluth opener in November.

LaVallee (No. 108 Pirtek/Polaris) was second, earning his fourth Pro Open podium this season, and his second of the weekend. Ryan Simons (No. 67 Speedwerx/Arctic Cat) finished third, netting his second of the weekend after winning yesterday’s final.

“I have really struggled this year,” said Martin, who padded his points lead with the victory. Martin now sits 21 points ahead of TJ Gulla (No. 44 Pirtek/Polaris) in the standings. “I’ve always been up there, especially in qualifying, but it just seems that something always happens to me in the final.

“I really needed this one,” added Martin. “This was a long streak without a win.”

Chris Kafka (No. 991 Pirtek/Polaris) won the Semi-Pro Open final, ahead of Dan Ebert (No. 602 Speedwerx/Arctic Cat) and Brett Turcotte (No. 196 Blair Morgan Racing/Ski-Doo).

Dylan Jansen (No. 272 Northway Sports/Polaris) won the 120 Champ final, followed by Kevin Kuklinski (No. 120 EmbroidME/Polaris) and Mason Hanus (No. 132 Woods/Polaris).

This weekend’s races will be telecast on SPEED. Please check local listings for dates and times.

The next event for the PowerSports Snowmobile Tour is the Air Force Canterbury Snocross, scheduled for next weekend at Canterbury Park in Shakopee, Minn. That event, another double national, will feature two complete Pro and Semi-Pro shows.

GULLA GETS PRO STOCK POINTS LEAD AT EAGLE RIVER

Press Release –

TJ Gulla (No. 44 Pirtek/Polaris) fought through fatigue, sore muscles and blisters on his hands to win Sunday’s Pro Stock final at the WPSA PowerSports Snowmobile Tour Eagle River Snocross National at the AMSOIL Eagle River Derby Track.

In the process, Gulla, from South Hero, Vt., took a nine-point lead in the Pro Stock point standings.

Gulla, who earned the top qualifying spot dominated the race, beating Mike Schultz (No. 5 Avalanche Racing/Polaris) finished second and sits in the runner-up slot in the standings. Iain Hayden (No. 93 Blair Morgan Racing/Ski-Doo), who recorded his first podium finish of the season, was third. It marked Gulla’s second Pro Stock victory this season.

“I was just trying to survive the weekend,” said Gulla, who finished third in yesterday’s Pro Stock final, part of the double national weekend here. “The conditions today were difficult, but they were the same for everyone. Before this weekend, I took some time off to heal to get ready for this because I knew it was going to be a long weekend.

“Every point counts now,” added Gulla. “Qualifying is important and you have keep the ball rolling. You can’t have one bad round. You really have to stay consistent this late in the season.”

Yamaha Made Its Point With Brainerd Win

Robbie Malinoski, Boss Racing and Yamaha made snocross history in January when they won the Pro Open Final at the Brainerd Minnesota WPSA National.

The Yamaha braintrust had to be literally peeled from their race trailer ceiling when Malinoski rode a near perfect final – pulling the holeshot and leading to victory on Yamaha’s all-new Nytro race sled.

Yamaha left Duluth in December, went back to the drawing board and built a brand new racer off the new 2008 Nytro platform. Clearly, the new Nytro is a very competent Open Mod snocross weapon.

There’s just no way you can under-value what this victory means. Yamaha said it was going to go racing against 2-strokes, and it did. Malinoski said he wanted to be the first to win big on a 4-stroke and he did it. Frankly, if Yamaha doesn’t do anything more for the rest of the season, it has made its point.

It was way back in late 90’s when Doug Henry won the Las Vegas round of the AMA Supercross Series on the YZM 400 4-stroke motocross motorcycle and made motorcycling history. He then went on to win the first AMA National Outdoor Championship a year later on a 4-stroke.

The mold was broken and now MX racing is dominated – indoor and outdoor – by 4-stroke power. While it’s much too early to make sweeping proclamations, we think Yamaha and Malinoski deserve a pat on the back for singlehandedly doing what most thought was impossible.
