[quote quote=89697]Will altering the squish gap change RPM ?  [/quote]

It’s actually the other way around…

Altering your rpm will change the squish.
I’ve had a 125 bike engine that was set up with .016″ squish, but if revved above 16k, would go to zero, due to crank flex.

Would start making a ringing sound above 16k, and when torn down both the piston & head would show light contact.
It never hurt anything, but I didn’t dare let it rev past that point.
I just used it as a shift indicator :)

I am sure this is happening on most engines to some extent.

Bump…

Not a real expert on time lines, but the K55 came out about ’78, and is still in limited production (it is a spec class in Japan).

Most likely the K11 was late ’80s-ish, and most likely vanished when the Parilla TT75 came out.

The major difference is that on the K55 the reeds/carb angled down toward the bottom of the cases, where as the K11 angled up towards the cylinder for better flow.

Someone make an offer on this package.

I have no use for it, and not into water cooled late model stuff.
