Oh, god. I can't imagine how many F-words I'd yell if this belonged inside the lower crankcase.
Well, a sigh of relief (for now). The regressive CB550 build continues - time to take apart carbs #2 and #3 and...

In-N-Out is not junk food. It's something to savor. Lots of gourmet burger offerings in LA but I wish they all could be a Double Double.

Spoiled brake fluid looks like spoiled cottage cheese.
I wanted to mock up the handlebar and MC/clutch and connect it to the front brake caliper to pump out and replace the piston but the old cottage cheese brake fluid has clogged the line and fittings... May have to replace the master cylinder parts now as well.

May be best of junk food???.....

Remove the m/c kits and clean them real good.  You may be able to reuse the old kits to pump out the piston.

Uh-oh. So trying to install the wheel. The disc side clamped down fine, mating nicely with the axle nut, like so:


But on the other side, the front axle doesn't quite make it flush or even halfway passed the axle clamp:


I loosened the triple tree clamp bolts to see if that would adjust the axle but nothing. Are the fender mounting brackets spreading my forks too wide? Should I squish 'em back in?

So, maybe these forks are slightly bow-legged. A little adjustment was necessary, so I loosened all the triple clamps except for one at top (disc side). With the axle in hand (sans wheel) I kept twisting the fork pipe until I found a good position. With each slight turn of the fork pipe I could see the ends of the axle protruding more to where I wanted it; flush with the axle clamp. That pretty much did it. Popped the axle back through the wheel, locked down the axle nut and lined the wheel back onto the fork lowers and clamped it all down via SohRon's assembly instructions. Voila. Merry Christmas ⛄️⛄️

Shopping around to replace my rubber brake lines... Interested in swapping them for some stainless steel ones (Goodridge). There's a kit sold by 4into1.com that comes with all of the hardware but with this disclaimer:

This kit does not retain the use of the stock rear brake switch, you must use a hydraulic brake switch or a master cylinder with a brake light switch built in.

I intend to maintain the use of my stock MC (replacing and making a bunch of those parts new also), so say if I purchase this kit, what would that mean for the stock rear brake switch and how would I make this work?

Not sure if you've seen, but there's a member on here that makes stainless lines & offers SOHC member discount. Might be worth checking out if you haven't seen.

This kit does not retain the use of the stock rear brake switch, you must use a hydraulic brake switch or a master cylinder with a brake light switch built in.

I'm not sure how anything you do with master cylinder in going to affect your rear break switch. Maybe rear brake light.

If the problem is activating the rear brake because the new kit won't l fit to the stock brake light pressure switch in the front brake system, you can always replace it with a banjo bolt pressure switch at the master cylinder. Also might help with some wiring clutter. http://slingshot-cycles.com/products-page/bolts-washers-switches/banjo-bolt-brake-light-switch-m10x1-0/. Double check thread size before ordering, he has two different pitches. If I'm not understanding the problem, ignore the above  ::)

I bought my stainless lines from slingshot cycles, as Bootsey said. Haven't installed or ran them yet, but they look to be quality and I have heard good things. Priced right IMO as well.

Thanks, guys. Slingshot Cycles looks like they have quality products (DOT-approved too). I'll check into it further...

Anybody use the Goodridge SS lines and get the rear brake switch to work with stock MC?

I'm currently in the middle of reviving my '75 CB550F, doing a little forum trolling, coming across this build thread was great!  So many tips to watch for.  Learn from others, right?  Thank you for taking the time to document so much information, I'm excited to see how the build turns out!

Thanks, kawabunga. Learn by watching how I screw things up :-)

Thanks for the recommends on Slingshot Cycles. I put an order in for some goods: brake hose kit, brake switch, speed bleeder (hope I ordered the right threading, M10 x 1.25). I'm anxious to get my front-end worked on again. Meanwhile, as I wait for those parts (including a MC rebuild kit, which I need to squeeze the front brake piston out), I've been thinking about how to mount my Phantom Battery (12V APP14A2-BS12) towards the rear, under the swing arm. Since I won't be relying on a center stand, I decided I'll use that space to mount a battery box somehow and came up with this:

Just a few Home Depot conduit hangers. Figure I'll customize a weather-sealed metal box and fasten some brackets to line it all up... Easier said than done, but hey, it's a start.

This guy came up with a clever and minimalist approach to mounting a battery around the center stand location. Looks simple but I can't figure out how he puts it together.
