It does. If you study the fiche for the ATV engine, you'll see that it has a clutch like the XR200, but instead of a cable and lever, it is actuated by a centrifugal clutch. The regular clutch lives in the regular spot, but the centrifugal clutch is on the end of the right side of the crank (rider's perspective). That's why the clutch cover is so deep.

If you want electric start, study the 200E, which was a two year only model (1982 and 1983). It has an attachment that sandwiches between the stator cover and the left case, and it houses a starter. The starter lives in front of the engine, which looks like an afterthought.

You can't kick a centrifugal engine of that design, so the pull start (and electric if you wish) must be retained. If the XR200 six speed fits in the bottom end of the ATC (and I'm pretty sure it would), you'd use the ATC crank, case halves, side covers and clutch and stator covers. You'd also use the ATC cylinder head, because the XR200 has a compression release for the kicker.

X2 on doing it yourself. It's a great learning opportunity.
