I just changed the belts on my 749 after reading thru the forums and watching every video I could find. After replacing them and buttoning everything back up except the fairings I did one last bit of research and found that CA Cycleworks is now recommending 99hz instead of the 110 hz in the videos. Bummer. So after thinking about it, I decided to recheck them as I set the belts at about 112-114hz. I had run the motor for a few minutes to make sure nothing was gonna blow. I didn't see why I had to take the tank back off, so I tried to remove the timing covers as the bike sat. I was able to get them off and checked the tension (after running they both checked at 102hz--very interesting). I could get the bike to TDC by turning the rear wheel with the bike in 6th--even with the plugs in. So why do all the work if it does not seem like you really need to? Or do the stock timing covers fit differently than the aftermarket carbon fiber ones on my bike? What am I missing?
