    I looked through the manual. The only thing that wasn't obviously something else and that might be it was listed as "Chain Casing." Don't know what else that could be. The torque was reasonable given the torque specs for other things that bolt into the wheel hub like the disc and the tone ring:
    8 N-m
    6 Ft-lb
    72 in-lb
    Calls for "Precoat"

    The manual says to replace any Precoated fastener. I figured I'd just clean it up with a brass brush and use Blue Loctite. Should I clean the threads on the wheel out with a tap?

    ???????????
    Which bolts/ nuts/ threads are actually meant here?
    The ONLY bolts in/ on the sprocket carrier are the 6 bolts M8x40 holding the rear sprocket to the carrier.
    And whatever the book says, mine will NOT be just fingertight at 8nm!
    Not on a sprocket that deals with 60 horses of a thumper engine.
    An M8 size at 8nm just doesn't make any sense.
    There's also no reason for those to be stretch-bolts (single-use), so (personally) I can't see anything wrong with re-using them.

    You know... I didn't even look! Is the carrier not bolted to the wheel? I just assumed the carrier was bolted to the wheel. I just assumed... Haha. Certainly explains why there wouldn't be a torque spec. I guess the swing arm and axle just hold it in place? :doh:

    The carrier is pushed into the 3 cush-drive rubbers/ dampeners which interface with the wheelhub. All is centered and aligned via the axle.
    Not a single bolt or metal-bit anywhere to connect hub + carrier.

    Ahhh. Danke. I've got some brand new Shinko 705s on my new Strada wheels. Haven't had a chance to put the wheels on because I had to have emergency surgery ten days ago to drain an abscess that went from nothing to nuclear in about 36 hours. Guess that's what happens when you hit 50:oldman:. (September) Getting better now and hoping to be back on the bike in another week or so. I figure with the Strada wheels, a Kouba link, and low profile foam from Seat Concepts I should be about able to flat foot the bike for town riding. A quick* wheel change and I'm ready for dirt! I like this Terra SO much better than the spongy, gutless F650GS. All this would happen faster if one of my novels would go bestseller!

    *Once I scrounge up an extra set of discs!

    Glitch, how did you find the quality of those low cost Chinese discs, OK I assume?
    I was very tempted by the price, but was concerned about the quality and ended up getting some used BMW OEM's (which most likely are low cost Chinese made too).

    Can't tell yet how long they'll last....fit was perfect apart from one issue.
    The mounting holes in the discs are recessed by ~1.5mm, which is not an issue on the rear as the ABS ring bolts to the hub separately.
    On the Strada (ONLY!) , the front ABS ring is mounted on top of the disc, all bolting to the hub with the same bolts. Needed a couple of S/S washers in each recess to pack out the recesses and get them flush with the disc-surface before mounting the ABS ring on top.

    Spun them both on the wheel-balancer before mounting and they seemed pretty well balanced. If they make 20-30.000mi of mixed road/dirt riding, that'll be fine with me.
