The 09 Rockers came with SE compensators from the factory. I took mine apart after 650 miles to see what it looked like. The boss and sprocket had some oil on them which they didn't have before I ground the grooves in the sprocket. I realize that 650 miles is too soon to tell how well the oil grooves work but I was in the primary to check out some other stuff so I took the comp sprocket off. It still made me feel better that some oil was on the boss instead of blowing red dust off it.
I bet you would like to know what the MOCO did to the new ones from the factory to eliminate this
Like you Hoople I think my primary runs smoother and I seem to have less vibrations on the footboards. Make sense if the sprocket can rock back and forth easier on a film of oil instead of fretting dust.That is Great news. Those 3 little grooves just may be the solution to this issue. Maybe it is wishful thinking but my primary sounds and feels better since I grooved that gear.
I might have to find the part number of the 2011 compensators to see if they are different. If they are I would like to have a look at one to see what's been changed.I bet you would like to know what the MOCO did to the new ones from the factory to eliminate this

That's easy Glider. They said the problem doesn't exist!
