Made a little bit of progress this weekend. The new crank is in, the case is buttoned up and leak tested, the new top end is on and squish clearance set. Gears in the trans and new oil and gasket keeping them safe. Unfortunately that's about all I got done, because part of my day job is working with kids, and the little disease factories got me sick.

But at least it looks like somewhat like an engine now, instead of a bunch of parts in fancy boxes.

EDIT: Forgot to mention, I'm making a point to do what Yamaha should have done in the first place, and all the bolts are 5mm Allen, No more stupid PH2 soft AF screws.

Those motors look so silly with that tiny cylinder on that massive chunk of a block. But those things can whip up some serious power.

Ya the minas look funny to me too. Malossi has a race motor I think it's a mina clone, and it looks like a racing aircompressor haha.

Our compressor at work is as loud as a 24hp gy6 without an exhaust pipe on it, does that count?
