Snowmobile Magazine Press Release - January 1983
There were several grand experiments at Eagle River this year. Perhaps the most publicized was lengthening the Word's Championship final from 15 to 25 laps. Could sprint drivers go 25 laps and would the sleds last? You Bet. Only one of the 10 finalists failed to make the 25 laps. The checkered went to Brad Hulings with his Ski Doo, who also won in 1981.
The other great experiment at Eagle River this year was a snocross program. What made this race work at Eagle was that there was snow to build a course with. In exciting finals, Jim Wergin won the stock class on a Yamaha SR-V and Todd Elmer won the open class on a Polaris Indy.
About 20,000 showed up to watch the racing action, which was about twice as many as a year ago. The windchill was 100 degrees warmer this year compared to 1982.

1971 RUPP MAGNUMS
In 1971 and 1972 Rupp Industries had
its banner years with over 31,000 snowmobiles manufactured
and sold in 1971, and over 40,000 sleds manufactured and sold in 1972.
Pictured on the right side of this page, you will see the complete line of the 1971 Rupp Magnum sleds. The 400, 440, 600 and 800 Magnums.
I was a Rupp dealer in those days, in which I sold one of each of The 400 Magnum, 440 Magnum and a 800 Magnum. These were beautiful sleds and hard to beat at the races.
On a spring-slushy day at the local fairgrounds, I
remember the 800 Magnum racing against four other
sleds. This sled was a half a lap ahead of the other four
at the end of the race. As the crowd was cheering and the driver cracked the throttle in front of the Grandstand, at
the final lap, there was a fishtail of slush about ten or fifteen
feet high.
The 400 and 440 had a twin cylinder high performance fan cooled Rupp/Tohatsu engines, the 600 had a three cylinder Free Air Rupp/Tohatsu engine and the 800 had a three cylinder Free Air Hirth engine.
All the 1971 Magnums had a slide suspension.

WHAT TO LOOK FOR IN A QUALITY 2 CYCLE LUBRICANT
Snowmobile Magazine - September 1988
Here is what To Look for in a Quality 2 cycle Lubricant:
1. BASE: A petroleum base with a low ash content, a quality synthetic base, or a petroleum synthetic blend that combines each of the previous characteristics, is the main ingredient in any lubricant.In addition to causing carbon build-up, a petroleum base oil with a high ash content can reduce fuel/oil ratios and cause a lean condition.
2. RUST INHIBITORS: Additives that prevent moisture from condensing on internal engine components are essential to a snowmobile engine.
3. DETERGENTS: Just like the motor oil used in your automobile, snowmobile lubes should include some type of detergents that clean your engine as they protect.
4. POURING POINT: As a general rule, 2-stroke oils aren't rated by weight. They do, however, have a pouring point which indicates the lowest temperature in degrees Fahrenheit at which the oil will continue to pour and perform to its full potential. When choosing an oil, make sure that the pouring point coincides with the climate you'll be riding.
GAS MIXING RATIOS FOR 1 GALLON OF FUEL:
20:1 Ratio = 6.4 oz oil, 24:1 Ratio = 5.3 oz oil, 32:1 Ratio = 4.0 oz oil, 40:1 Ratio = 3.2 oz oil, 50:1 = 2.6 oz oil, 80:1 = 1.6 oz oil

YAMAHA BEEFS UP SR-V for 1982
AUTUMN 1981 - There will be an SR-V of a different color out on the cross country circuit in 1982. Yamaha's trail racer is now black and its new macho look is matched by a beefed up engine and new high-performance clutch.
The SR-V gets a power boost from 56 horsepower to more than 60 horsepower. The extra horses have been added via larger reed valve assemblies and larger intake and exhaust port dimensions on the 536cc axial fan-cooled twin engine.
The SR-V also gets the new Yamaha YSR drive clutch, which promises increased durability and performance. Another change is in the seat, where more comfort has been added by removing the rear storage area and replacing it with foam.
