2500 miles on this sled i bought and looks like the clutching will need some maintenance just based on running it around the yard and fields.  Seems to work well at higher RPMs but not as it should IMO at the lower range.  Engagement is running around 4200-4500 and i'd like it about 500 rpms lower for my kid. I see that the spring is purple blue at 160/290

 

What is the spring load on the secondary spring so i can cross reference and get some aftermarket.  

 

thx!

The secondary should be 14-16 lbs with a fish scale.
 
Just get brp primary spring.. possibly the one in bold.

i did find that ibackshift.com after the fact.  Still navigating around a skidoo as i've always had Polaris sleds and know them pretty much inside out.  

 

What would you suggest for a secondary spring considering the spring isn't available anymore from Bombardier.  part # 414558900

You do not need to change your secondary spring..  just use the chart above but personally I would keep it in the stock holes. It wont effect engagement at all. 

 

If you use this spring (130-290 BL/BL 414689400).. it will drop your engagement just like you want. Going from 160 start to 130 start.

Two revs is right you don’t have to change secondary spring but probably a good idea as then you won’t need to do anything but keep them clean and inspect them for a few years. I would say if it’s a stock spring given the age I would change it if it were me and for 30$ saves you from putting the primary together and finding out that the secondary is spanked and having to wait for parts and mess with em again

Figure about 100 rpms per 10# change in force. So going from 160 to 130 initial force will drop your engagement about 300rpm's. It'll load the motor through the rest of the shift until full shift. Should work well.

this is what i was thinking as well.  $60 in springs for the rest of the season and i'll go through the clutches when putting them away
