Seems I always have a question. I'm getting ready to do my first valve shim check on my 06 America, it's 3,000 miles late but I finally have time to do it. I do have a couple of questions though. I used the rear tire to align the lines and dots on the camshaft gears and the "Top" is at the top on the camshaft drive gear. My first question is how critical is it to remove the alternator cover to align the mark on the rotor with the crankcase mating surfaces? My second question is are the crankshaft holder bolts (torx) extremely tight? I do have a hand held impact to use but am worried about cracking something if I use it. As always I look to the experience and knowledge of you guys and gals for the right answers. Thanks for any help.

'06 America, Raask foot controls, the bike use to be Graphite and Silver, now its Red and Black.
