This is my first post, and would like to say I'm not much on posting. Just reading! I enjoy this forum because it seems to be more informative on the machanical end of the bike, and has different places to go and look for the information.
The reason I'm posting is I have an 2010 Limited. I put 255 cams in, an air cleaner, slip ons, and went with a master tune. I've talked to others on the Limited and what they've done and it seems like the compensator was the next thing. So, today was the day and I choose to grind my case instead of pull it. I'm not sure if they have a different casting or what, but mine took very little grinding. I did grind the black off than pulled the rotor back to the grind, then I took a piece of paper and found my tight places and it was only tight at the bottom. A little off there and the rotor came right off. I did pack rages around the clutch (which I left on) and around the rotor. For those thinking about this change, its a very easy one with minimal work, just alot of cleaning. Brake clean.
I work at the factory that makes all the beveled washers that go into the compensator (no I can't get any) and I can say that there was a lot of years into the development of the heavier ones. It does upset me that they didn't go to this on all motors. All washers are heat treated, then drawed back and set at a height, then ground (top and bottom) to a very close tolerance,peened and heated again. Maybe not all in that order, but a lot of hours go into the washer. Also, I would like to say I paid for mine. I would also like to thank those who put in the HOURS on this forum.
