Snowmobile Mid Season Check Up, Is Your Sled Running Like It Did Back In Nov.
Now that you have been riding your sled for part of the season
Is it running as good as when it first hit the snow?
There are things that you need to check that wear or get out of wack as you ride.
First lets take a look at the drive belt:The clutching on a sled is the heart of it’s performance, it is what allows the engine to rev to it’s max horse power RPM. (shift rpm) more later.
An easy way to check the belt for burned or narrow spots is to ride your sled from a dead stop and very slowly accelerate to about 5 or 6 mph (this should only move you 20 to 30 feet). If you feel any jerking or pounding as you pick up speed you have a bad belt and it really should be replaced.
These narrow spots allow the sides of the clutch to move in and out each time the bad spot goes by and beat the heck out of it, after about 10 to 15 mph you won’t feel it any more, but the damage is still being done to your clutch.
The other thing to look for is normal wear (the belt will wear narrower) and sit lower in the secondary, If it gets too low the clutches will not shift correctly and it will be like taking off in your car in second gear. No power off the line!! If you want to maintain that like new performance this is also time for a new belt.
So how does the clutching mechanism work on a sled you ask, here is a simple explanation:
Next lets take a look at the spark plugs:Pour or missing spark is one of the primary performance robbing problems. Start by removeing them and take a look at the center electrode, porcelain color-it should be a light chocolate brown Not black and shiny. If they don’t look great,
replace them—it’s an easy way to keep your sled starting easily and there cheap. On replacment spark plugs, I highly recommend the NGK brand. They have a wider heat range and just start better and last longer, just my opinion, after 40 years of experience.
