  • Sled:1989 Skidoo Saga 377

Posted 21 November 2020 - 06:30 PM

The sled is a 2000 Yamaha venture. 
 
If not following my journey, the short summary is that I noticed cracked skid rails after buying and so I replaced the entire skid.  In the process and to prevent this from happening again, I also changed the shocks and these are the original coil springs put onto Kimpex cheap gas shocks. 
 
Both the front and back shock behaved the same when tested out of the sled, very hard to compress and slow to rebound.  Figured that's what they're supposed to behave like?  But never done this before so unsure.  
 
The previous owner had the coil springs cranked almost all the way down, and so I left them both relatively loose 3/4 of the way out.  
 
Skid went back into the sled and immediately noticed it's much more compressed with even just the weight of the sled.  When I lift the back to get it on the dolly it will sit higher like this picture shows:

But if I put any weight on it it will collapse down to this point here and not go back up to fully extended as in the first picture.

I have to take the skid out again anyways because I forgot a washer behind the front W arm bushing and so I might as well solve whatever is going on here. 
 
From my complete inexperience I'm thinking along the lines of a) the original coil springs are completely fatigued and/or B )   3/4 of the way out is way too loose and the spring isn't giving enough resistance to support the weight on it 
 
Thanks again for all the help guys - it's been an adventure!

Hi Michael, been following your problems and hats off to you for sticking with it. By chance, have you ever been on Totally Yamaha web site, years ago when I had a Vector I got a lot of info there. Good luck.

I believe those shocks are gas emulsion shocks and will not rebound on their own. They are sealed shut and not rebuildable. If I recall, that type uses oil to control compression and rebound, but not much of a gas
charge helping out the cause.
If the rebound is not coming up, you have a spring issue or something is binding preventing the rebound.

See? Even us Doo riders can help out a fellow sled set even though it’s a Yamaha guy!
