I went to that page but the only video I could find on it was of someone teaching a cat to jump through a toilet seat.

I put a 55mm 272 wiseco piston I make it’s a lot easier build to do with the 390 cylinder and I had a 272 54mm made too the piston is ultra light and string

The squish band to bore ratio is high in those pics, like 70%? You running a lot of squish to keep the msv down? I don’t do Facebook! lol post those videos up here!

Finally got out to run my hot mess of a mildly ported big bore 372/390 "85cc" on Saturday. I'm pleasantly surprised how well it ran in the wood. It's much more enjoyable to run than when it was stock displacement. Just plain has more grunt.
