Reeds are a one-way valve located downstream from your carbs, mounted between the crankcase and cylinders. The motor pulls the air/fuel mixture from the carbs, through the reeds and into the case.

When we started Project Foreman we knew that one of the areas that we'd have to address was tires. The manufacturers of ATV's try to provide a general-use tire that's a jack-of-all-trades and master of none. What you end up is a tire that's ok, but not really good at anything such as being a good mud tire or one that works well in the snow. After getting stuck a lot with the stock tires and using a winch more often than we cared for, we knew the stock tires weren't enough to do what we wanted and needed to accomplish. We use the Foreman for trail maintenance all summer; the smooth winter snow trails are creek beds and mud holes all summer. We needed a change.

Now that I?ve covered the basics, let me share some of my real experiences with you. I made up my mind from the beginning that I would buy a sled just for racing. I usually turn my trail sled over every year for a new one so I didn?t want to race that one. I chose to start racing with a 1997 Ski-Doo Mach1. This choice was based on:

Some tracks mix the snowmobiles with the motorcycle in the same class, some don?t. It varies by track. The track I race at has not combined the bikes and sleds so I have not had that experience just yet.

Consider that you?ll run your sled to get to the staging lane, down the racetrack and back to the pit area. Total running time? 5 minutes, if that. So how hot does it get? Through the hottest days of July with temperatures in mid 90s my sled never cracked 210?F. Typically the water gets up to 160-180?F. The most critical time for temperature concerns is after the race. The water stops circulating when you turn off the engine. Then it heat soaks: the water temperature will go up as it soaks up the heat from the engine. When the engine and water temperatures have stabilized at their peak, then it will start to cool down. So you should have a cool down cart. Generally, the cool cart consists of:

I make the following disclaimer on this story: I am not a veteran snowmobile racer or mechanic. This is a story of my limited experience of half a summer of asphalt bracket racing. I?m sure that there are those of you reading this that have far more experience than I do. I welcome your constructive comments. I?m sure the rest of the people reading this story would welcome your input as well. I wrote this story because I talk to a lot of snowmobilers that have heard about this activity but don?t know how to get involved or where to turn for information on getting involved. For those people I hope this story enlightens them as to just how easy it is to get started in this exciting sport. It?s a shame to leave your snowmobile sit in the garage all summer long when you can be racing and learning.

An ATV suspension kit from a company that make snowmobile suspension kits and the amazing Snow Hawk? snow bike! This is a first for a company like A.D. Boivin who has been working magic for the ill riding suspensions on snowmobiles from ski-doos, Artic Cats, and Polaris. We've testing the ski-doo MXZ 600 ETS system and the resulting improvements turned a bucking bronco into a trail pony in about 45 minutes of work. I wouldn't own a ski-doo with the SC-10 suspension without one. The SC-10 will never be a smooth and comfortable suspension, but the A.D. Boivin ETS kit did help considerably.

You can make your stock skis into asphalt legal skis or buy aftermarket skis specifically for asphalt. The majority of sleds I?ve seen have purchased asphalt specific skis. My recommendation is to buy aftermarket skis. In the long run it?ll be a lot less hassle. If you make your stock skis into asphalt skis, then you won?t be able to use them on the snow anymore. Also, with the stock ski conversion most racers use stock idler wheels as the wheels in the skis. My observation on this is that the idler wheels do not stand up to much of a side load before the rubber starts coming off. If one of them blows the rubber you could have a handling problem. By my causal observation at the tracks that I?ve raced at, the most popular skis are the ones made by Whal Bros, followed by the USI skis. Both of these skis use a single wheel in front and rear of the spindle. Here you see sleds with 3 different kinds of skis

Powder riding and off-trail excursions are what I live for. I've been known to drop out of long distance trail rides and go off wandering through the trees and over little hills to see what is out there. I really like deep bottomless powder, some relatively small hill climbing and boondocking out through the countryside. I am rarely the guy that goes furthest up the hill but am one of the guys that always shows up to help stuck people get unstuck. I'm a pretty big guy, a shade over 6 foot, and 225 pounds is a fond memory, so when I do get there, people are usually glad to see me.
