If your brakes stop working, do you just drag your feet?
Some people say if it ain't broke don't fix it. I say if it IS broke, fix it.

That actually happend to me to first motor on my bike. The guy sold me a not running bike cheap to find I needed another motor. Exactly your same problem and spot. JB Weld won't do it very long, and cost over $300-$400 for a machinist to get it welded on with precision. You have 2 options for the cheapest fix, 1. get another motor 2.Get the oem block off of a website and replace the block and piston rings, www.bikebandit.com has them.

Radiator off helps.
Then just make sure all wires are disconnected. 4 plug wires (its easier if you take the coils off), fan switch wire, kickstand wire. There may be more.
Put a floor jack under the motor and unbolt the mounts. It helps to have a friend hold it steady. One good thing is that the F2 motor doesn't ride on the swing arm pivot bolt, so that can stay on.
All of the mounts but one are normal. The bottom rear, you'll likely snap (because its so long, pretty skinny, and likely frozen in place), so if you could source a spare one, that'll help. The top rear mount has a "cap" on it (left side) that uncovers are large allen head. I think its around 10mm. So you'll need a large allen socket.
After all mounts are loose, just move the jack down a tiny bit and forward, engine should come with it.
Don't hold me to exact specifics, but that's the jist of it.
