    Lots of rust and stuff on this one from a 1990. Was going to throw it in a ttr230 conversion. Think its still salvageable?

    I would be most concerned about wires and their connections. All the big heavy parts will probably clean up and work OK.

    Leave the magnets be! Do not remove them. The outer metal drum acts as a keeper for their magnetic field and if disturbed could mess them up.

    Scrub them down with a non-magnetic brush & solvent and call it good. m.

    I'm pretty sure those parts are '87, not '90.

    The previous owner must have put the 87 electrics on a 90. Will have to find a way to mount the 98 rectifier on a 90 fram. Mounting spot is different

    Is it possible he put the entire engine from an '87 in it?

    Interesting. Those parts are '87 though, because that's the only year they were like that. One ignition winding, one lighting/charge winding, four magnets. Just like the offroad-only BW200. They changed that for '88.

    i removed them once and the bike seems gutless, starts, idles and runs fine..just no power on acceleration..could this be why? i did wonder if they were + and - and i'd got 1 the wrong way round. not sure how much power it had previously because i've dealt with so many and can't remember this particular bike.
