Homemade 4 stroke (project lmz)

[Will'smotobikes19]

This kid made a homemade ohc 4 stroke. I like it because he started with 3d printing it and started using more metal parts. He needs to work on a cooling system as the cylinder is just a plain tube, no cooling fins. He's building a vtwin too.

I've watched all of it since he started 3d printing it. It's a pretty awesome project and a great way to learn exactly what makes an engine tick lol

If its a 225 slant six, that tick would be the tappets, (valve lifters)...lol...lol.

The good ole leaning tower of power. That's my second favorite engine of all time. My favorite of all time is the briggs 5hp flathead.

Straight 6's are my favorite engines, 300 ford, 250 ford. Chevy had one I forgot the size. It was in a 72 nova I had. Easy to work on and love you long time.

Yes venerable old motors 216 and 235. Run for years and years with almost no maintenance. Oil change? What's that?
As long as you kept oil in it, it would run.

Chevy's inline 6 was a gutless wonder. But yes, they are very easy to work on. I gutted the emissions and tuned my teacher's 80 c10

Did you also ramrod the catalytic converter to trash the screens and innards so it looks like it's there but actually has no further functional purpose???...lol.
