Re: First mods, case reed engine
See the cyld with one wide upper port, I take the 2 upper port cyld and Dremel out the center pc with a 3/8" barrel cutter. It's pretty easy, Then I run a no port piston. Learned that from Sam, ( Boosted306 ). On the cut cyld it don't have to be pretty, the head is going to cover it. The most important part is the top where the copper head gasket sits, the side of the barrel only has to slip into the head, I use files, sand paper, ( wet & dry is the best ) mostly, and the barrel cutter around the outside of the ring. When I was machining alum & plastics way back, I make a small surfacing block out of 1.5" Thick alum, its very flat, made it to do may drag bike stuff. I use double sided poster tape on the block and put sand paper and go to work, lol. I buy one sheet each of 100, 240, 400 and even 600 ans 1,000 grit, $1.30 a sheet. You could use a flat piece of glass.
