    and of course it would pretty obvious when apart
    if you are already final assembled just for curuiiosity see if there is any gap
    try a .001'' feeler gauge,see if it will go in at various flange locations

    The front end has been completed. The seals needed replacing and I got the extensions from XB, so they came apart and went back together. The VZ triple, with its lazy offset, is gone and now we're back to a full TL1000r front end. It took a little more steering stem gymnastics to make it all work out. The bike should be sportier with this configuration and comes with plenty of lean.

    hey eric here is some images of the kit i fabbed for my tl
    originally i was using the tl clipons above the triple utilizing the cap extensions
    then i went full on mx bars hence the bar risers bolted into top triple
    i also nedded to raise the tl windscreen so i put in the rotating assembly in stem
    i have the female half just left it at the storage unit
    i drilled a drainhole in each cup after i discovered rust would be an issue
    although not a structural deal because the 1/4-20 shsc are sealed up with red loctite so water cannot get to the threads
    they have a 1/4'' thick bottom and a shallow centerting ring to get axial allighnment
    they allow 1-9/16'' to raise the front end,however once past 1.3'' the bottom triple starts loosing purchase because of tapered section begins
    obviously you have no issues with these being the top support, but it's not something i'd really considered before. how tight do you do them in the top of the fork tube? would you expect any flex in the threaded joint?

    i would not go past recomended titening tork for a cap
    or are you talking abbout the extension fastening ?
    the 4 1/4''-20tpi shcs i put in tight as i dared and fixed them with redlocker
    it is a very strong jont where the extension joins cap

    yes i have been thinking of that when used as clipon high mounts the cap threaded joint is clamped by the triple,same as when used as a stock setup
    this effectively prevents any squirming around because the threaded cap on these forks are from my expeerience a nice class a threaded joint not sloppy
    i do believe the outer tube needs help after warshing the idea around and when miller posted up progress with fitting them i figured on a suggestion
    i think a very close fitting sleave with .098'' wall thickness out of steel or ss 1-1/8'' long and a near perfect fit bonded in place with red loctite
    it may be totally uneeded but it is a very simple thing to fab and it def will help keep unclamped tube top from belling
    the bottom triple is 5mm larger for the tube fatness down there
    going 2.5 mm wall thickness still maintains ease of removing bottom triple
    it could be made fgrom the same material a fork part
    it is a very high sttrength allow on every one i have turned in the lathe
    fitting the sleave with loctite allows easy removal
    its lovely stock to turn in the lathe upsidowner forks everybody should have some

    I always have to read your posts like 5 times to get the gist. LOL

    Small victory for me by now finally having the TL top triple is being able to mount my key switch on the tree. I don't like the BMW headlight mount and I didn't like my decision to mount it on the side cover. The side cover had it's advantage in that it took less wire to get to the battery and such, but the location was a little weird. This makes more sense.

    I'm going to the Flanders Euro low bars and I machined some caps for the fork extensions out of delrin. I may cast these in urethane, though they should be fine as they are.

    You do some nice work. BTW, what is the ctr to ctr on TL forks? I have some GSXR in 207 and 214mm widths and a couple of odd ones that I suspect may be from a TL

    Thanks, Teazer. I assume you mean the triple measurements? The forks themselves are 50mm top and 55mm bottom at the trees, which makes them different from the 600 and 750. The Hayabusa and the K9/K10 1000 share these measurements, so you may be able to at least eliminate or confirm the 600/750 and the other 1000s.
