I belive the worst that could happen has...

Had I visited this thread earlier, I could have given you some feedback on the Dyna S for that particular model

Anyway, you've probably already figured this out, but the Dyna S 3-2 rotor + spacer combination is usually a bit too tall for the factory EI bikes, and when bolted in will not allow the rotor to advance (hmmm, maybe that's intentional and why their instructions say to time to the full advance mark even at idle ). Anyway, at least one person I've consulted with didn't notice and had idle issues. Swapping out the spacer for a thinner washer did the trick for him. Personally I sanded down the top of my rotor by about 0.7mm.

LOL Well funny you should state that... I used the Search feature (Noobs apply) and ran into your thread with the fellow having issues timing his 550 for idle. I used you advice and pictures as reference to setting up my Dyna S. It fired right up with no adjustments FYI . As of now I have the rotor sitting in there with no spacer so it moves maybe an 1/8-1/16 of inch back and forth. I plan on grinding down the spacer or buying a thinner washer once I’m 100% satisfied with the timing so it allows the advancer to well advance without wiggling back and forth!

LOL So Thanks for unknowingly helping me out any way
