Machining idea, try making a Hemi head and go one step further one with a domed piston and not like those new Chrysler HemiI've been nibblin' away at this cylinder head. 10 thou at a time and it ain't all that bad. I get into a zone I call being "One with the Machine" and the time just flies by. What I have to be real careful of is getting zoned out and cutting too far!
But I do have some issues to still work out.

One is it's missing a slot. I couldn't reach it! The Y axis bottomed out before I could get there. I'm gonna have to clean all the aluminum snow off the mill and remount the mill vise to get that one.
At .140 wide the fins are too thick too.

The fins on that head in the background are .090. The cast fins on the cylinder are only .050. So I'm calling this just a rough cut. It still needs some trimming.
Something I figured out along the way is the .155 endmill I used is way too long. It has a 1' reach and I only need a half! I'll betcha a shorter cutter would've got me a lot closer to the .030 cuts Tony was talking about ...
But so far so good. I'm learning.
Greg, you need to build a new workshop! I have the room here but no $$$ to build one! I should play the lottery I guessYesterday afternoon a neighbor up the road came down and offered me a craftsman radial arm saw, said he needed it gone and would help me load it, if I keep getting free stuff I’m going to need more space. I am tempted to build something for all my wood working tools, keeping everything in the shop means moving something every time I need to do something with wood.
Row Boat!Keep the faith. I just received a set of brass horn holders from Australia that I ordered March 17. I think they came by ship instead of air.

Fired up the little 49cc and put some miles on so I could change the oil and keep it limbered up. I was temped to sell itKeep the faith. I just received a set of brass horn holders from Australia that I ordered March 17. I think they came by ship instead of air.

The drive clutch will get dry from lack of graphite on the plate and there is noise from the pins on it. SeveralCvt is good when it’s brand new but when you run it for a while it does get noisy. Keep the jackshaft and run a clutch instead...
Cheaper than a 125 swap too.. l I like an automatic motorcycle... ride with one hand most the time
Yes, a properly setup cvt will smoke an improperly setup clutch in any comparison.The drive clutch will get dry from lack of graphite on the plate and there is noise from the pins on it. Several
fellas have tested the clutch drives versus the CVT on minibikes and the drive clutches will get so hot that
become orange in color when pushed on steep grades and can't pull the grades when they heat up because
of slippage. The CVT tested against them will go right up the same grade with no problems. They've been
tested on YouTube against each other in several videos.
I'd bet a 212cc will burn up the clutches in a lot of city driving and in the hills. The way to go with the 79cc and they areI know they are pricey EZL, but the EZM transmission is second only to the Sportsman Flyer, Bully clutch/ reduction drive. The former is a improved Whizzer transmission. But you with your 212cc are a candidate for a https://3dmotorsport.net/collections/manual-clutches
