So I just bought an 09 M1000 snopro with 800 miles on it. It's got the SLP pipe kit, PCV and Cutler's clutch and adjustable weights. I'm going to school and here in my town we have a dirt drag for sleds. I'm very confident nobody will beat this sled with that pipe kit and the clutch so it's an easy 300 bucks.
What I need to know is how do I prep for this?[/QUOTE]
What you
need to know is that your M1000 isn't very fast (compared to race sleds). I have a 800 Skidoo XP 162 mountain sled that will beat you every time. I have never lost a drag race to a M1000 or M1200 for that matter and real race sleds will beat me.
I'm not hacking your sled (or bragging about mine) so don't get all spooled up...just trying to put it in perspective for you. You are about to go abuse your "mountain sled" on some dirt where it has no business being to win $300. By the time you pay for fuel, entry fees, etc. you might make $200 (assuming you win). It sounds like you just bought the sled and are making payments on it (or something). Now consider your going to trash your hifax, track, bushing, bearings, scags, skis etc. There is no snow to cool your sled on the dirt so they like to get really hot! My guess is by the end of the day you will have done more than $300 worth of damage and wear n tear on your new sled.
Now if you proceed with the race here are some helpful tips that may help you to not get beat to badly.
First off try to park as close to a water source as possible. Bring a garden hose a spay nozzle with you to the track. Every time you make a pass swing over to the water hose and hose off your track and skid to help clean, cool, lubricate the hyfax and such. Also run cold water on your cooler for a couple minutes to get motor water temps down.
If you have any clutch parts add some weight to the primary. Put in a primary spring with a low initial number and low finish rate as this will help your sled shift faster. Your M1000 has plenty of gear in it for 500' of track. If track is 660' then your gonna get passed on the big end by sleds with better gearing but not much you can doo about it with a diamond drive.
Let your limiter strap out at least a hole or two and soften up your rear shock a bit. This will help weight transfer for more traction.
When you are at the starting lights and ready to go hold the brake on and bring up the rpms a bit to help build a little heat in your pipe. Too much rpm for too long and you'll know it from the blue smoke coming from your belt but you'll figure it out.
Most decent mountain sleds should run about 80-85mph and cover 500' in 5.6 to 5.8 seconds. That should give you an idea of how fast (or slow) your sled is.
Good luck and have fun!
