^^^ Seen it many... Many Times... I still do not see the need for such complexity and adding a source for even More Problems!!!
This wiring arrangement works, it is not complicated, and goes a long way toward eliminating starter run on.
Like all electrical systems, it requires a bit of maintenance, such as cleaning the connections periodically, all starter circuits need to be maintained, even the newest stuff.
I like to wire the bike so that the original switches do the job without any extra buttons, etc.
Everyone has their preference.

Why use the old fashioned relay at all?
When I did my friends bike I went from the battery to pin 30 with a 20 amp fused wire and then took a wire from pin 87 directly to the solenoid.
Worked just fine.

You mean like O.E.??

The way I like Mine as well... But, Never thought of the 20amp fused Wire... Interesting...
If I ask HD they would say I could not build this bike. 1963 Shovel heads ,electric start ,Electric ignition , 5 speed trans. one up 4 down ,open primary, belt drive, Check out the jugs big boor, this cant be done but its sitting in my driveway and did say its fast too.So you can do just about anything you want to do.
Using the blue streak relay helps reduce the chance of the starter to run on.
Sometimes the solenoid has a problem retracting the plunger, (sometimes the friction between the pinion gear won`t allow the plunger to retract, but cutting power to the solenoid will eliminate this issue.
The reason the small 5 pin Bosch type relay is used is to protect the starter switch (connecting the switch directly to the blue streak relay would pull a lot more current through the switch.

If I was afraid I needed such a set-up... I would certainly use a Washer or a Quarter, on the Solenoid..Course.. if one refuses to maintain a good Battery... even that will fail...so the one small complexity I do Not mind [tho rarely incorporate in my Bike] is a Ground Cut-off!!! Very Simple... very Cheap... and don't Fail!!
BTW; Replace that Fugly Ford relay, with the old tractor starter Bagga shows, and really have safe and Easy...
I still have the ford relay and it works fine. I just added the "old tractor" switch as a back up because I had some bad luck with the ford relay. I added it because of the problems with the relays. a guy I use to work with is a ford guy and he had a pail of relays, he gave me several.

FWIW I can tell you running a wire direct from the switch to the relay won't work as the wire isn't big enough to carry enough current to do the job.
That's what my friend tried before he put in the piece of feeler gauge on the solenoid (he lost his relay on the road somewhere).
The only reason I put the 5 pin relay in was to make is button work again.
