    You can simplify the gearshift by using a GS500 one like I did on my Bandit. See the pictures, the shift pattern even stays the same.

    Slow and steady is ok, its one of those tools you have to get a feel . No big radius jobs on it atm . A mate had a old Australian made army one it bends nicer than my china one .

    Water jet swingarm parts are cut .
    Knocked up a bracket to hold sidestand switch in the up position .

    Spent a bit of time trying to workout out leading link dimensions .

    20200531_173548.jpg

    Then off to see a mate and measure his . Probably won't be built the same way but measurements are in the ball park

    20200529_191938.jpg

    Next weekend might see a mocked up swingarm and a tacked together partial chassis .

    I wonder what thickness Ali can be water cut?

    i don't have a water jet cutter so just use a big mob that do.
    They can cut pretty thick stuff but i doubt you could get bores accurate enough for clamping forks even with the 5 axis cutter.
    You could get a blank cut out with most of the material removed and then bring the important bits to spec on a manual mill with boring head.

    That would be cheaper than having it cnc machined and probably a bit easier than manual machining the whole job.

    Who ever your local waterjet cutter is might be able to organise the whole job for you.

    Me likes it. But I’m not so sure about the small bolts. Have you calculated the sheer on them? I don’t know what to expect in use so I usually way over build. But I’d rather build light like yours if I could be more sure of the actual loads.

    No I haven't. My partner in crime is smarter than i and i trust his work even when my own brain is farting numbers eh @DRjoe .
    Just going with the size of the original shock bolts . Most holes are 8 or 10mm on the parts .
    It's all shock and swingarm adjuster related
    Did some load numbers when making the subframe and there are 2 bolts that I would wince at . The thing is with the other 2 larger bolts and the clamp force it was surprisingly good. Real world testing will tell .

    Are your meaning the 3xm8 bolts used for holding the removable swing arm section on?
    i haven't run the numbers, not smart enough for that as im not an engineer.

    The original idea was to use m8 shoulder bolts in reamed holes but i think it’ll just be plain m10 bolts now with maybe 2 locating dowels.

    We’ve also designed in a key and keyway for the swingarm plate to locate on but that was more to aid in assembly when changing a tyre.

    would love any suggestions or feedback.

    I don’t know what the loads are on the removable swing arm. Probably not too much unless the axel is small and wants to flex. I might add a 1/2” dowel or two just to be sure the bolts don’t sheer. Here’s a pic or two of how Claude built the one I now have. His swing arm is a bit different. I like yours better. But I up sized the axel to 22mm iirc when I installed the rim from a Suzuki dl1000. The rim he originally installed didn’t hold up to my abuse!
