Sad to say, but here in the next week or two i'll be putting my '09 Nytro to bed until next winter. At one point (either on here or on ty4stroke) I thought I saw a topic about weather to change the oil now before storing it, or to just wait until the fall and start fresh. I can see an arguement both ways so I want to see what you guys think. Also, any other tips/tricks/advise you can offer me? First sled..... Thanks!
