Shit the GL1000 only has an 5 gal tank and gets 200 miles out of a tank, the 550 should get more than that between fills with 9!
Hahaha.  I'm totally kidding.  9 liters more like it.  This tank is around 2.5 gallons, maybe closer to 3, but definitely no more than that.  It's a Gen 1 CB750 tank shortened, narrowed and shaved.

Ha, I didn't look that close to it, I may have noticed. You still should be ok for at least 100 miles

The tail end of the subframe points upwards a little much for me but that’s just my opinion.

The stance makes me think flat tracker.... you should build a flat tracker out of a 550. I triple dog dare you.

Haha.  It will certainly have some tracker queues.  That is for sure, intentional and part of the reason for that subframe.

I would say having 20mm ID bearings and a 17mm axle is a good reason to make captive wheel spacers.  The bike is looking good.

This is what I did.  You could say that's what they are.  I machined the black pieces in the drawing to adapt the wheels for the smaller axle .  I'm calling them sleeves.  Everything presses together so that the sleeve flanges line up with the bearings' inner race. Grey is the hub/bearing assembly.  Blue is the outer spacers.  Yellow the axle.  The 550 comes stock with a captive spacer outboard of the sprocket side.

I had an XL350 rear wheel lying around, but a PO welded the sprocket carrier to the hub. With the size of the sprocket, I’m guessing it was some sort of hill climber or something. Instead of going out and spending a bunch of money to swap for a different wheel, this will get me a 36 spoke hub to put an 18” rear wheel.

Yes, I’m throttling back and forth on wheels. LOL. Still waiting on Buchanan to get back to me on a spoke invoice to convert to a 17” front wheel. So the dilemma is whether to go 17/17 or 19/18. 17/17, is likely the way, but I need to spin a bit longer.

Regardless, it was fun to unfuck an XL hub...

My new handlebars came in, along with my 2.5 x 17” DID GL rim to build the front wheel. Hopefully spokes will be in from Buchanan by the weekend. I did also get spokes for the rear wheel that came in today. Fortunately, the same spokes will build a GL wheel and a wheel with a GL rim and CB550 hub.
