    Spray cans on the frame are ok, I've done it before when money was an issue.

    I do think that sandpaper on the rims is a bad idea.

    Extra fine steel wool and wd40 will do a good job of cleaning up the rust.
    Better to go ahead and take the wheels apart first. That gives you a good shot at cleaning up the rims.
    Spokes can be cleaned up with wd40 and a rag. Don't use an abrasive on those zinc plated spokes.
    Clean the rims afterwards with de-greasing solvent, and paint the areas that were rusted with phosphoric acid to neutralise any remaining traces of rust.

    Re-assemble the wheels, and take them to a shop to have the spokes tightend and the rims trued. It's worth the expense and time.

    (see you in a couple of weeks, Sttg?)

    I was wondering about that.

    Might as well pull the cylinders, new rings, port it, mill the heads, new seals, expansion chambers....

    Pandora's box.

    I would take a serious look at the crank seals.

    +1 Now's the time! It's easy to pop the cases apart and send the crank off for rebuild. Well worth the time/money. The last thing you want to have happen is to get the engine reinstalled in a nicely painted frame and find it doesn't run well and have to yank it out again.

    Don't ask how I know... :rofl

    Somebody educate me on crank seal significance. I heard my seller speak of crankcase sealing, but I didn't understand him. He was probably refering to this item. Can they go bad, sitting up in the engine in clean oil?

    Thanks to all for the suggestions. I'm the blind leading the ignorant when it comes to mechanical expertise. But I try to listen....

    There are seals on each side of each of the crank lobes, so thats 6 seals that stop anything leaking between cylinders. Over time they get brittle and start cracking, if air leaks in the cylinder runs lean and very bad thing happen.... like seizures and holed pistons.

    The seals do not sit in oil so having oil in the engine is not a cure.

    A leakdown test will give you an idea of their condition but personally unless I changed them in the recent past or was positive someone else did I would (and did) take it apart and see what shape they are in. You will save money and heart ache.

    Once you get to that stage,if you have any doubts at all about the crankshaft (and sitting for years will do them no good)
    Contact Damon Kirkland... he has a world wide reputation for crank building...fwiw

    Put the triple tear down project on hold during the triple digit Louisiana summer. Just started back. Trying to get the stator rotor off the side of the engine so I can split the cases and get the crank sent in for repair.

    But first, I need to order that special bolt puller tool to get the stator off.
