    My pieces and bits have arrived so there is nothing left to it, but ta do it.
    The rubber intake boots went on like a glove no problem there, they are a i-vm28-200-1 mikuni flange 60mm bolt holes and 35mm intake.
    With the cable spacers i went from too much slack to not enough so i had to take about 12mm from each end and re tap the threads, i will use the adjustment to balance the carbs. i took a stab at the jetting and went one up on the pilot and three on the main. (stock 25, 112.5 running 27.5, 120)

    I gave it a start, dialed in the air screw and it seems to idle nice and was revving up strong, but we'll how we go when we start a on road tune. next up the tank, let's gett'er done.

    Please take note everyone. The air screw (not fuel screw) is on the air cleaner side of the VM carb. Turning those things does very, very little as opposed to a fuel screw, (what most on this forum have) which is very sensitive. These air screws are best left at some number of turns out and fuel screws should be tuned by ear as opposed to n turns out.
    And keep up the good work Napolian :)

    i can feel the end is not too far away, i am now getting the tanks organised. fuel tank i've started the body work and primed up ready for fine fill. i should get the paint down this week.

    as for the oil tank, im changing the way the fittings mount to the tank. just had to solder up some holes and tap the other one with 1/4bsp.
    i discovered the tank is aluminum covered in chrome and to so they do something with copper and somthing somthing vodo magic. short story i sanded it up a bit to show the copper. i think it looks sweet.

    p.s you guys thought my last shelf was sweet check out my new one. :thumb_ups:

    i'll have to get back to ya on the solder, it work's only on non ferrous metals.

    got the paint down and it come up a treat, used the heat of the roof to bake it, cleaned out the tank with diesel and a vacuum cleaner. i would never get a tank sand blasted again, it was really hard to get it all out.

    next is oil tank than test and tune.

    hey guy's happy new year to all and hope you had a great xmas, In February in will be 4 years since i picked her up from kiffstas place, this may be one of my last post's in this thread as the suzuki for the most part is finished. a bit more tuning down the road but its running ok for now.

    take it back about 2 months i had just got her running and i was having a lot of trouble with the plugs fouling turns out that the 2 stroke oil line check valve was letting oil drain from the tank to the crankcase and it would run for a bit then start to mix and foul the plugs. at the same time the kick stand bracket snapped and that led to me pushing it to the corner for a bit.
    so i got some other oil lines and made a new kick stand setup that im so much happier with.

    the spark was a little weak and if the turned hi beam on at idle the engine would shut off, so i had to run a battery over the emulator.

    tuning was a real pain in the ass, started a little bigger than stock being that the new carbs are the same size as stock but after stuffing with float levels and jets, it turns out the main was way too rich.
    that should be about it for now.

    Congratulations on getting it all done, and it has both a front and a rear mudguard.
    I think it would look a bit better if you could tuck the chambers in and up at the back. Now about all those other project bikes that appear to be in the shed. :)

    That's fantastic. In this photo it looks like a cross between a speedway bike and a Bobber...well done, very unique.
