    +1 on the 36mm six sided socket. AND an impact wrench.

    I used to torque the cap nut to specs. Then I read on here somewhere more than once about using impact wrenches that approximated the appropriate torque to tighten the cap nut. I happen to have one impact wrench that fits the bill with both a "soft" setting and a "not terribly more powerful" setting. :D (I have others that are a little too powerful for tightening but great for loosening).

    The plus side of using the suitable impact wrench to tighten the cap nut is that I avoid the risk of tweaking the fork tubes out of parallelism by holding them while tightening the cap nut. Very little leverage required to hold the triple trees when using the impact tool.

    Yes - I'm with you on torquing cap nut but bearing nut is adjusted by feel - thank you for double checking.

    I couldn't torque with my crescent wrench so set bicep on pretty friggin tight and buttoned it up. I'll pop the bars off again when I get my gianormous 36mm hex - practice makes perfect.

    I am starting to think I should go ahead and drop the forks. My omega 450 is on back order but Rick is saying soon. Schedule being what it is probably be early Jan before I get to tinker again - we'll see. That'll let me take a look at the bearings, replace the boots and lots of working room for new wattage. :clap

    I've started reading on forks and some folks report this as pita. I'm sure I'll have a few moments - fun stuff :thumb

    Use what you got!

    You like your KTM front end? Worth the bucks and time? I'm not sure where this bike will take me but a po did Wilbers rear and progressive springs in front - suspension changes not on my short list right now. Might take you up on wrench offer. Using the drift to tap it around worked ok but more tools!! Maybe a trade or fair market value?:ear

    What's popular thinking on running a stabilizer on these R80's :hmmmmm

    Na....show up at one of our gatherings and it's yours. We gotta stick together!:freaky

    I do like the front end, and it has been worth it! I abuse the crap out of the bike, and the stock forks complained on several occasions.

    In the old days, maybe. BMWs from the '90s onward have torque specs for the adjustment. They work pretty well; from what I've seen most DIYers adjust the bearings too loose when they go by feel.

    I've never considered putting on a stabilizer. The bike doesn't need it if properly maintained. As for the rear loading side of the equation, I refuse to install a top box of any sort but stick with the standard BMW side cases. I will put my tent/sleeping bag over the top rack but that's about it. I like the thought of a clear exit path behind me in the event that I have to lay 'er down...

    Haven't seen anyone talk about relieving the pressure on the upper triple by also loosening the clamping bolts on the fork tubes so everything moves in parallel when you torque the head bearing...then tighten the fork tube bolts. Makes for a more precise adjustment

    +1 or that top clamp will have a smirk.

    If anything I think mine could be more loose than they are now - based on the description in service manual of falling gently to the right when unweighted. Bike is an 84.

    When I got the bike steering seemed perfect. Maybe 3 seconds from center to right. I've turned the bearing adjuster nut one full turn lefty Lucy - with drift and soft blows. I can probably count to 10 it drops so slowly to the right now. Not sure how the PO rode the bike, maybe my trails are taking a toll?

    Makes me think that I need to see more innards. Grease & bearings - perhaps I've bent up something - don't think that's the case but level of abuse is new ground for me. Seems strange that bearing adjuster nut would get so tight given that cap nut was a beast to loosen.

    Lack of experience doing the talking. :lol3

    My set up is soft luggage with very small waterproof and powered top box, no tank bag. The bike came with BMW side cases but not expecting they'll see much action. I mostly travel light except when I don't :freaky

    I'm not actively shopping for stabilizer but have found them pleasant additions on some bikes - perhaps somewhat safer as seems to reduce odds of bitch slap even if maintenance is off schedule a bit. Might help on days like Sandblast too (I have airhead rallye wants if not skillz. :lol3)

    We'll see what happens / where this beautiful beast takes me and how I treat her, we're just getting to know each other at this point.

    Thanks for that, should have 36mm socket - will append torquing to include that.

    New tool came this week - much better than crescent wrench. :norton I took the bars back off, then loosen cap, further loosened head net then torqued to 120nm. I'm concerned though, doesn't seem right.

    Look how much space.

    And here is the gentle drop to the right

    NO CRESENT WRENCHES.

    Buy some tools. A man can be defined by his tools. You can never have too many tools. :D
    The deal I have with my wife is ANY home project {over a few hundred dollars} and I get to buy one tool, sometimes more. That keeps me moving forward on my tool ownership and makes each job that much easier and me looking forward to that next project....happy wife, happy life....more tools=happy daddy

    #7 should be used to take up the play by pressing on the top of #8 (the crhrome retainer).

    Makes sense.

    I'm loosening 7 because steering is so tight - right? Seven also does the job of setting pressure for head bearings. Seems like it's looser than it should be but steering has much greater resistance than it did when I first bought the bike. That's driving me to believe I've got dry or damaged bearings and need to drop the forks.

    I do have SOME tools. :lol3 Just nothing as big as 36mm. The crescent is a travel wrench.

    You would have gotten a big smile to see us adjust chain tension on a Duc with a pipe wrench. :D
