    Picked this up last night, and just like the title says, I'm not sure what to do. I can take anything apart and put it back together, but my knowledge on 2strokes and motorcycle transmissions is limited. I'd like to learn more.

    It was supposedly sitting in the same spot for the last 20+ years
    It's pretty complete
    I don't have a key or title. Title shouldn't be a problem...
    The shifter moves both ways, but nothing happens.
    Right side engine cover is loose, and everything that you'd have to get out of the way to get to it is missing (kicker, footpeg, etc)
    There was a bolt threaded in place of the spark plug

    Clearly it was running, then it wasn't, and someone started digging into it then quit.

    Do I...
    1. Rebuild/replace the motor, get a key, and ride it like it's 1987
    2. Make it into something cool/custom... I've always thought it would be cool to put modern suspension/wheels/brakes and motor in an old enduro. I know I said my 2stroke knowledge is limited, but I do have access to legit fabrication/machine work.
    3. Part it out

    Fix it and ride the tar off of it more or less as is.

    If you want to put modern suspension and stuff on something, I don't think this bike is it.

    Typically a bike like that will cost you more than it's worth to restore it.

    Bolt in spark plug hole? :hack Pull the top end to see what lurks inside. Pull that side cover off to see what might lurk in there too. Not good that the oil filler cap for the trans is missing. Transmissions were pretty strong so doubtful that it could be toast, but the all of the bearings could be rusted. Easy to check the clutch while the case is off too. Crank seals on the older two strokes that have sat for any real length of time will leak and need to be replaced. That's where I would start before putting a dime into it.

    Modern suspension will improve it but the old dual shock bikes are limited to the amount of travel available. You might get a real plush 4" of travel out of it.

    No doubt on the cost/value.

    And my vision for the modern stuff on an old bike isn't really for performance, just a fun bar-hopper/conversation piece.

    Any recommendations on the key situation? Pull the ignition cylinder and take it to a locksmith?

That is a dummy plug where you can put a spare plug in case you fouled the main plug. Or if you wanted a different heat range. Assuming there is a plug already in place. Can’t tell on my phone.

    Now that could be. Back in those days guys racing scrambles/TT on two strokes also put compression releases in the "extra" hole.

    Naa, an operable key-switch is for later-on down this road you're on.
    Don't spend much money 'til you know more.

    "Hot-wire" around the ignition switch for now.
    Tend to transmission and oil-injection; case integrity & oil levels.
    Clean-up carb & air-box.
    Then, see if it runs from a remote fuel tank.

    Yeah, the tank was my immediate concern. But remote tank makes way more sense. I'm also 99.9% sure it won't run as is, so I guess I'll just thinking about further down the road.

    Today's news:

    complete clutch assembly: awol
    rotating assembly: seized.

    Not surprising. Still disappointing.

    That is really just a part bike. Unless it had / has sentimental value, it's not worth messing with, I know this from experience, more than once. :roflWhat I have learned about buying old bikes is, they should be complete, unmolested, and since I'm in California, they must have a signed off title with no back fees, generally speaking.

    To me it depends to the overall status of the bike, if it would be mine I would taje it aoart and evaluate the complete bike then do the guessing math of costs and add 100%.

    Then I would think about if it us worth and also take time in consideration.

    If I have enough time and if I like to rebuild bikes I personal would do it. If not I now can sell it in parts.

    To the bike, it looks very nice, if rebuild proper the engine is also very nice, you can get better suspension for it you can even pimp the engine to 200cc.

    I have the trialsmodel a TY and I am very pleased,butthisparticular bike needs a lot of work.

    Parts are not so difficult to get, of this bike many where build soare parts are easy to find.
