    Motor swap 1987 to 2001. Different stator

    Hi I’m trying to do and engine swap due to my 1987 TW200 blown motor . but the TW200 2001 stator is different to the early model. Can someone please help me with either advice or a color wiring diagram

    It would probably be best to pull the flywheel and stator out of your 1987, and install them in the 2001 engine... or just swap the flywheel, and use the whole 1987 left side engine cover.

    That way, the wiring will just plug back together.

    You might as well pull the right side cover also, and swap over your kick-starter guts, and maybe service the clutch.

    Nothing can be simple, huh?
    Now I must hurry on... for there they go, and I am their leader!

    You are attempting to swap a 2001 55W DC stator into a 35W AC frame — ‘aint gonna fly

    The problems this throws up are horrendous

    For a start off, you would need an entirely different wiring loom to reflect the increased wattage, together with changing out the CDI, headlight bulb, and God knows what else

    As CJ7 suggests, you need to put the ’87 stator on the thing, together with the original ’87 crankcase cover, or you’re onto a hiding to nothing

    Then there’s the kickstart issue …..

    CJ7's advice is spot on.

    p.s. Tw200eac - just so you know, the bike shown in your profile pic is not a 1987 model year TW.

    Have you pursued idea of getting an output shaft extension from forum member PlacerLode that allows an almost direct replacement of the TW motor with your XT motor?
    I did this with a TTR223cc motor and am very happy with the results.
    Unfortunately you will need to use the complete TW ignition system & flywheel so will have to source an '87 stator.

    Tw200eac – you may have noticed that your multiple posts on this subject have now been moved into the one thread

    So you now have a thread covering the use of an XT engine, and this one, covering the use of a TW engine

    The posts have been moved simply because they are two completely different subjects, please don’t take offence …..

    Fred – post #7 seems to have migrated across as well, but we can live with that given that Tw200eac now seems to be concentrating on the TW motors, rather than the XT swap he proposed last year, which your reply pertains to

    (Told you it was going to get confusing) …..

    Not sure if this helps or has been covered. 87 stator that year only. Next 88 to 97 all same. Next 98 to 2000 all same. Then 2001 til now. Stator and wiring harness and CDI must all match. I can tell you what year your stator is by the colors of wires on it.
