I just noticed a very small spot of oil under my Sportsman 500 EFI after about three days. The leak must be extremely slow, but there is only 300 miles on it. It looks like it is coming from the side mounted screw on the bottom. Has anyone experienced this?

 

I've not read about it hear. Did you try to tighten the screw. If that does not work call the dealer and see what they say. My delaer is good they've taken good care of me so far even on iffy items like my belt.

 

Sidemounted screw could be an oil line. Mine was leaking there when I brought it home new. Just tightened it up and all was good.....

 

A better description of the "side mounted screw" would help a lot here, like where exactly it is located. A picture of it would be even better. If you do decide to tighten it yourself, be sure not to strip it otherwise the dealer will not cover it. If you're not sure and it's convenient for you, take it to the dealer and let them check/tighten/fix it. Good luck!
