You ever worked on any of the aftermarket Krauser 4 valve heads on BMW stuff from the 70’s?I ran VHM two piece heads back in the 90's. I still have a bucket full of them, from 10.2cc's and up to around 10.8cc. The outer shells are gold colored. The trick heads have bronze inserts in the squish band to quell detonation. The inserts would eventually crack, but then, racing ain't cheap.
My 64 had the earles too. Great handling little bike. Not much power but fun to run around on. That crank is pressed together and has to come apart to clean the slingers. I have never done that. The /5 model like the one I kept is not as good looking but a much better motorcycle.I need to take the engine completely apart on mind and clean out the built up sludge in it. Mind has the Earles front end. Love the look of them.
That in farmer inches? That's 1.27mm, ain't gonna have any problems with a canyon that deep. My .45 is 0.0177 farmer inch.Yes planned on using hollow core solder and we are going to be at about .05 squish which is way better than the .110 that comes from the factory.
I am working on something much bigger at the moment and for $200 it checks a box that I no longer need to worry aboutThat's very pretty, but I'm curious why you didn't just fire up the machine and make it yourself
I know, I know. . .
Design, programming, setup . . . blah blah blah
when CZ Eddie started his bike and I walked up behind him with a bolt and said this just came out of the silencer. The look on his face was priceless.
