I need to get mine out. Just finished tuning the carbs. Now to see if I finally defeated that off-idle flat spot.

Oh.....veeeerrrry coool Jim. Those are hard to find in nice shape and worth big money hereabouts.
My uncle Dave has a 1971 Mach III (Kawi 500
H1) that he bought new in 1971 for about <I think> $1150 CDN. It is blue and had the two-leading shoe drum on the front and the factory CDI ignition complete with the centre-fire plugs and a faint little hum when you turn on the key. He still has it and rides it every summer. It is in showroom condition and has never been wrecked, dropped or rebuilt (he is often told that it is one the few early H1s in Canada that has never been put through a fence on a back road or flipped over on a small-town main street).
EDIT -
of course the Mach-III 500 cc bike is an H1 and not an H2. Sorry about that! To make amends, here is a photo of bike that is identical to my uncle's machine.
The last time I saw it, he had just under 20,000 miles on it and it was still a 1-2 kick start bike. I actually rode it once - and it is actually pretty stately off the line (unless you slip the clutch) but once the revs hit about 4-5000, it is like GOD kicks you in the @ss, your ears are assaulted with the din of 1000 atomic bumblebees and the world behind you disappears in a blue haze as the front wheel begins to skip off the ground. If you cranked it on while in a corner.....well, it likely wouldn't end happily.
Everything people say about the peaky power, wobbly frame and "21HP brakes on a 60HP motorcycle".....
.....is true. Having said that, I think that the later bikes were much more manageable and steadier handlers and the front disk brake has to have been a major improvement.
Nonetheless, it is a very very nifty bike and I'd love to have one.
