Just done a compression test on my sled. The Sled runs great and my compression tester is brand new. It says I only have 110 lbs of compression. The Sled as only 600 miles on it. Any suggestions? Im fairley new too the sled world.

Was test done with both plugs out and throttle wide open?

 

[shanetbaker]

Yes it was... S the Sled starts fine in extreme cold conditions too... It was -35 C last night and she started with the second pull this mourning.

Have you tested other sleds with it? It may be reading low from the factory?

 

[shanetbaker]

I actually tested it with another tester and got between 115 and 120. I compared it to another 2009 dragon and it too has the same compression.

I'm wondering if there's a decompression hole in the 800 to allow it to pull over easier.

2009 dragon

i was looking at buying a 2009 it has lots of miles on it close to 2000 , i ran a compression test and got 115 and 110 and the same while it was hot. I cant get a straight answer as what it should be brand new, the dealer said 125 was minimum but i think that guy was high. I have the canadian tire special tester 30 bucks so i dont know how accurate it is.
