Most "custom builders" and especially those calling themselves "cafe racer builders" are producing garbage that isn't worth riding. Virtually none of it would pass a proper inspection in Ontario. The bike in your sketch will not certify, I know my insurance company wouldn't touch it and moreover it would be a real pileocrap to ride. All flash and fluff, no real stuff. The problem with cafe racers is "that are primarily built to the liking of the builders themselves" and the vast majority like what doesn't work.
Thanks for the replies. My purpose for posting on here was indeed to get technical expertise advice as I go through the process. Hence why i didn't just finish the bike and post a picture of the done product in the Pictures thread.
To summarize, the forks were already slid up into the triple tree about 2" from stock. I took them apart, cut a 3" piece off the main spring, used it to replace the rebound spring (a.k.a. shifting the resting depth of the fork), and cut a PVC spacer to make up the difference on top and add a little bit of extra preload. The forks do need new fork seals which i'll do further down the road, i want to sort out the engine first.
Here is a picture of one fork shortened and the other in its stock state and slid up to.

Post a picture of the crankcase damage. Do you have any idea how the damage occurred? Usually occurs because something really bad happened (like a brick wall). Begs the question... what else is damaged. Unrepaired frame damage? Remaining mounts cracked/damaged. To me, it makes no sense to spend money until you know exactly what you are dealing with.

It is indeed a curious case of how the hell did that happen.
I was planning on buying one of these and completely replacing the bottom crank case of the engine:
There does seem to be a slight dent on the frame on that corner. Based on everything else i saw on the bike I would not be surprised if the engine had been taken out and dropped on that mount point, and snapped off. Alternatively it could have been some sort of other high speed impact like Cyorg said. The remaining mounts are in good condition. When I bought the bike it did run and I did ride it home for about 2.5 hours (which in retrospective was probably one of the more stupid things i've ever done, given the condition of the bike). So it would appear that the damage is only external. Disassembly will show the full condition. I mean for $400 CAD one can't really expect much.
Read up on crank bearing selection just for starters.

Good point, i've entertained the idea of grabbing a working engine or even a parts bike. I'm willing to learn and I'm certainly not doing this for the profit of building a custom motorcycle and selling it. Profit is not at all why I got into this. I have a passion for motorcycles, for the countless hours spent in the garage covered in oil, for the overwhelming gasoline smell of carbureted motorcycles. So all in all I have the time (not in a hurry), I have the drive, and i am willing to learn.
I never thought about the fact that the cases are machined as a set. I did notice that all the ones for sale are sold as a set, and it didn't click in until now. Thanks for the insight.
I managed to finally pull the carbs apart with the exception of 1 of them.
I got one of the screws that holds the air box bowl to the carbs mostly stripped. I soaked it with all sorts of things and it would still not budge. Any suggestions on how to remove it?
