looks eazt to maintain

Nice, beefy looking timing chain on that baby...The oil filter's in an easy spot to reach, too. That looks like a pretty massive cam sprocket with a damper on it..hmmmmm...on the camshaft...or is that a balancing shaft? YEs, there's the cam shaft below with the 3 cam bearing caps. Overall nice looking configuration and compact for sure.

That's not ours. That's a turbo version.

I'm not too sure about maintaining an engine with all three pistons at top-dead-center at the same time!!

This also appears that possibly it isn't a direct overhead cam engine, but possibly a "high cam" engine.

But, no knock at all there from me, with a few productive motorcycle road races while "up" on the 250cc Parilla "High-Cam" single in my resumé. (I was a whole lot lighter in those early '60s days.)

Ihoboy,
So this one is the 11.4:1 or the 10:1 engine?

Pass me the compression gauge. I'll let you know.

(All the turbos are 10:1. Ours will be 11.4:1.)

Pistons aren't at top dead center. Those are the plug locations.

Great pic!
Even though this is the turbo version, it is likely pretty much the same basic engine, minus the the turbo, the exhaust manifold and some water and oil lines. On the two engine I have and am familar with with-the 4G63 (2 liter I4) and the 6G72 (3 liter V6), the N/A and turbo version of engines are virtually identical except for oil squirters, pistons (which is where the compression is changed)and the camshafts. I would expect this will turn out to be a similar situation. As for that dampener, I think that is the MIVEC mechanism, which allows change of intake valve timing.

micronuts recent tech info thread, said usa getting a 10:1 not the 11.4:1, to allow different qualities of gas, etc.

I would think the lower compression will also add to engine longevity.
