Alright well here is the build thread for my 1987 Honda Spree.
Bought it not running on 3/9/15 and took it for a ride that night.

There's the video of the first start
As you can hear it didn't sound too good
Tore it apart and here is what I found
So let the rebuild begin!

All torn apart

Little score in the cylinder wall

what did you clean the head with? the flat surface needs to be machined flat .Also the head needs to be milled to suit the larger piston if not squish will be way off.Make sure you use a crank puller to fit the crank into the cases other wise you can untrue the crank .

I cleaned the head with a wire brush and am using a sharpening stone to smooth the gasket surface. According to Taz the head does not have to be modified.

I broke a crankcase bolt and it flew threw the stator, so I ordered a new one. Should be here tomorrow, then I'll see if it'll start.

Thank you!
I was super * at myself for not using fresh crankcase bolts. But I just chalk that up as another lesson learned.

That wire brush put a lot of scratches into the aluminum head gasket surface.

Correct. I smoothed it down perfect using a sharpening stone.
