My name is Robert Bianchi, I own this motor you see in this video.
So let me explain how hard it was to sink a 54mm sleeve in this jug. VERY DIFFICULT! Your worried about the sleeve being off on one stud? have you ever thought about the 4 holes in the jug aren't square from factory? You just assume I don't know what I'm doing?
This isnt a simple build and this is the FIRST one I've done with a 52mm. Ill have it running in a week when the rings get here. Hopefully everything turns out well. If it does, I will be selling these. If you want one contact me, if you don't that's okay too.
