    Project build thread "Machi akuma" Suzi gr650

    Not a gs, but a GR figured you guys may be interested:

    This will be the official build thread for the new suzuki, dubbed the "Machi Akuma" translates to "street demon"

    Plan on approx 6" or rear stretch (or however much i can get going from a 104 link chain to the 130 link i ordered)

    Some fairly extreme rake

    This bike will be a long and low jap chop to just toy around on. She will be amazingly stable on the highway, but will have the turning radius of the titanic...haha




    The to-do list:

    1)Tear down

    2)Repair engine (cam chain adjuster, part is en-route0

    3)Hack off the rear of the frame

    4) Adjust rake (may end up doing a gooseneck)

    5) Fabricate exhaust

    6) Fabricate Seat pan

    7) Setup seat suspension

    8) Modify trailer fender for use (have to section about 2 1/2 inches out of middle)

    9) Fabricate axle mount taillight and license plate holder

    10) Fabricate forward controls (DONE)

    11) Fabricate forward control linkage

    12) Gusset additional frame at stress points

    13) Install new chain and see if im going to need a chain roller of sorts

    14) Fabricate battery box

    15) Wiring

    16) Assembly

    17) Shakedown ride





    I know I'm missing a few things, but I am operating on 2 hours of sleep right now..lol will add as they come to mind.



    As she sits Right now:

    Assuming you are using the same sprockets, the same amount of chain will be used in the curves around them.

    Your new chain is 26 links longer, so 13 will be on top, 13 will be on the bottom.

    If you have a 530 chain, it will be 13 * 5/8" longer, or 8 1/8" longer.

    If you have a 630 chain, it will be 13 * 6/8" longer, or 9 3/4" longer.

      Hey, thanks for that! Looks like I will be shortening the chain, As I dont think I want more than 6" of rear stretch

        Just figure out which chain you have. The numbers on the chain will tell you.

        530 chain is 5/8" from pin to pin and 3/8" across the inner plates.

        630 chain is 6/8" (3/4") from pin to pin and 3/8" across the inner plates.

        For 530 chain and a 6" stretch, 10 links will get you 6.25".

        For 630 chain and a 6" stretch, 8 links will get you right there at 6".

        Don't forget that the extra length needs to be on top and on the bottom, so add either 16 or 20 links, depending on what size chain you have.

          excellent. its a 530, I already ordered it. When I ordered the chain for my last bike I lucked out and it was the EXACT length i needed, so figured i would just go with one i knew was entirely too long this time to be on the safe side

              thats the plan my man! im thinking, since i and going to rake it, i may as well just start with the headtube and make the frame 100% custom
