I have read the forums this last season and have seen all of those who are struggling to get their '11 and '12's running properly. My 2011 Pro 163 never ran like it should. We checked everything from top to bottom, replaced the top end, swapped working parts, etc. all to no avail. My sled would never tack over 8150 at 6000 ft. with polaris 61 gram weights. That's a problem considering that we ride between 8000-10000 ft. (Side note-the pistons did have back wash and were slightly discolored at 750 miles beneath the rings. Rings were in good condition-after replacement there was no change in performance.)
However, on a ride about three weeks ago my sled shut down and wouldn't start. The motor would fire when we added fuel to the pistons but would not run. Upon examination, we found that the d**n brake wire was rubbing between the air box/fuel tank area. We later found that the short had taken the stater out. We replaced the wire and the stater and took it for a test run.
We could only engage the throttle about 1/4 before it would hit rev limiter. You could ease into 8300-8400 RPM and then hammer down which would immediately shut the sled down. 61 grams was not nearly enough weight. The sled is now an animal and I can't wait to ride next year.
Check your brake lines.
