Hi everyone! Im from Italia!
I started to assemble the engine of my 50cc Malaguti f10 (Minarelli-yamaha short case)to bring it to 98cc taking example from what has been done on this forum. the cylinder is a TWH d54 that I will mount with an Athena race 43mm shaft. does anyone know this cylinder? what performance have you achieved? I noticed that the piston head(top) is very rough, have you polished it? thank you! Sorry for my terribile english!

Welcome to the forum Ricardo.
I'm not familiar with that cylinder. But post a build up so we can follow your progress.

Great work so far man welcome home, Lol. I was born in America but M so Dang proud of my Italian blood anything to do with textiles or machinery or are even Artwork if it's not from Italy it's not top quality. I may be biased... I have try to make this exact cylinder work I had to mill the case to allow for fitting also notice that the piston casting at the top was poor quality However I never got to finish it as my 41.8 mm stroke was a hair shy I ended up cutting the top off the cylinder to match the stroke but by that time I realized it would not have a Great-Power band due to that anyways look for to your build and about that read cage with the 2 different channels in it I have seen those before online and always wondered how they would work out on A 2 stroke moped let me know what you think or what you Already know about these read cages as I find them fascinating also found intakes that have the same to channel design kind of thought they might work like read stuffers in the effect of channeling the flow.
