#1 Absolutely check the oiler screw (there's a thread on it already)
If it's not turned up already, 2.5 to 3 full turns gets you to around 40:1. If you do turn it up check your oil usage closely and do the math for the ratio.
#2 At 1100 miles you're approaching a top end in another 500-700 miles. You may want to do all that now for peace of mind
#3 Consider a quality clutch kit. I had mine done last year. Improved low to mid range torque and smooth backshift.
#4 Consider adding reinforcements to the tunnel around the footwells. If you mainly boondock/tree ride and explore you probably don't need this but if you like to go big on jumps and drops you WILL eventually crumple your tunnel. Contact AKSNOWRIDER for info. He builds a great kit for the Pro.
If you've got the jingle burning a hole in your pocket consider a long rod conversion. I just had mine done but I'm keeping my 12 for at least 5 more years.
And if you decide to leave it as is, it's still a great sled. Keep it clean and serviced and go ride.
