It sure looks loose to me. It really doesn't matter anyway since once the axle nut is torqued up it ain't going anywhere. Those bolts are only to move the axle for adjustment, not to hold the axle in place.
...or maybe it's some trick factory thing :confused:
I really doubt that his mechanic leaves anything loose, even if it's not critical. That's why I was asking.
Zorro- I haven't seen a KTM chain adjuster up close or haven't paid attention to it...I'll check it out.
pro2K- The geometry of the new Hondas' rear suspension allows the to run the chains with very little slack. Also he's on the gas already so any slack would be on the bottom run. Also, the rearend is already settled down so most of the slack is taken out.
Ansi is right about the nut.
As for the tension of the chain: I think it comes from the way Factory Honda has mounted the upper chain roller, high on the subframe and not on the frame above the footrest...
