    Thrust washer.

    FYI, with a lot of the aftermarket covers you have to use more than one to space the bendix correctly.

    I think it's both. Trying to set accurate timing with the TDC mark only is bad practice. And of course running a motor with the pipes glowing is bad practice too.

    H,

    It's a good thing you have...

    Before you shell out any coin for a left side case that old, find someone you trust, who has the knowledge to inspect it. A loose main race boss can render the case unusable, or at the least, mean...

    First, resistor plugs were used with point and coil ignition since resistor plugs were invented. What do you think they were for? Some say that resistor plugs don't work well with magnetos. In any...

    Look at your battery cables. Are they tightly connected at both ends, and are any of the cable terminals cracked? I have seen ground cable terminals crack almost through, and so pass just enough...

    2000 rpm may not be enough to fully advance the mechanism. It's best to have someone rev the motor while you look at the mark. It will continue to advance, moving toward the rear of the hole, until...

    Are you sure of the timing mark you have identified as the advance timing mark? It should be a dot, low in the hole, on your '83, IF, and that is a BIG IF, the motor has the original flywheels. (On...

    The countershaft has an oring to seal it. The earlier transmissions with the cap did not have an oring originally, but of course a countershaft with oring could be fitted. Clean it good and use your...

    Those links are used to align the chassis. The motor, transmission, and swingarm are one piece, and the frame and front fork are the other. As long as the bike hasn't been wrecked, and the various...

    The caliper takes a 3/8-24 banjo bolt. The fitting is a 3/8 banjo 3AN 90 degree. The brake line is 3AN. The flare fitting on the short line is 3/16 inverted flare. It has a 3/8-24 thread. Wrench...

    Yeah, those things are thin, thin, thin. I wonder how many of them will end up broken, sheared off at the corner. Certainly a clever adaptation, but no thanks.

    Of the carbs in your box, the butterfly Keihin would be the easiest to tune on an evo. You will probably find the Bendix to be too rich across most of the midrange as they were best suited for a...

    There was a "dual smoothbore" carb setup available for shovels and ironheads back in the seventies (?) and eighties. It had dual 29mm carbs, but on a manifold that itself was fairly restrictive. They...

    One of those tank vent tubes is just a drain from the filler neck area to handle spilled gas. The other one, I think the one that is soldered up, is for an evap system that your bike might not have...

    You will have to fixture this frame very rigidly on the mill table, which might take some imaginative clamping. Then you can just drill or single point bore it out. It's just clearance, so no real...

    If you choose a Dyna S, DS6-1, that is the dual fire version and Dyna offers a 5 ohm coil for that. Andrews offers a 4.7 ohm coil that works well, too.

    I think that is the same material that I recommended. They are available as a five plate clutch as well.

    Glad you got it sorted out. A good shovel clutch is a pleasure indeed.

    Should have been, or could have been, both. If the OP has paperwork to match the case, there should be no issue. If f. has no PAPERWORK, yes, he is truly well fucked.
