Here's an update on some of the logistics of a grubee skyhawk and an onyx frame.
The first thing I had to tackle was paint. I used Rustoleum high temperature paint. I picked it up at Autozone for only 8 bucks. They had a variety so if you want a pink engine, it's covered. I would suggest to anyone new to motors, not to take it apart. Use a lot of masking tape to cover the rods and big things, and as for the holes plug them with wet toilet paper (this is ghetto, and its fragile, but works!) after that just paint. If you don't know how to paint, maybe you should just install it.
MOUNTS:
The rear mount should have been an easy fit but the bracket for it was a little too small in diameter, so to overcome this I filed the inside with a round file until it fit snugly.
this is just an example of where to file, I didn't wanna un-mount it just to show you.
The bottom large adapter 15$ extra and it worked ok. The first thing I did was remove the bolts that go into the bottom of the engine completely. After cleaning off the bottom, I attached the supplied "large frame adapter" plate to the bottom of the motor where I removed the bolts. I used 2 hex-bolts found in the Grubee skyhawk kit to do this. I don't remember what they were initially for but I ended up not needing them. After securing the plate to the motor with the 1" hex bolts I cut out 4 rectangles of old tire tube to fit the plate. and fit them under the plate as shown.
After I fit everything together i realized there was one problem, the u-bolts for the large frame adapter were a bit too long in one case, and I had to cut off about 3/4 of an inch to make it clear the engine itself.
As you can see here, the back rear thread needed to be cut.
After all those minor mods, it fit together well.

My fork looks the same one as yours. The cable front brake works OK but I could see upgrading to a hydraulic one sooner or later.
