To me it looks like you need to rotate the brake plate anti-clockwise about 120 deg and mount the brake stay forward of the axle. This would move the cable to run almost up the springer leg as well.

Having some issues with the carbs on my chopper.

Took them all apart, cleaned, soda blasted and polished them.
While apart I installed Honda OEM gasket kits with new orings.
Set the floats to 22mm using a Honda OEM tool measuring from the base.
Also checked to make sure they were sealing by blowing air via mouth into the carb fuel in and holding the floats at 22mm.  They drop a bit and air flows, at 22mmm no flow.

Installed on bike and they leak.  Some times.
Some times it's like a garden hose and fuel comes out the drains and out the mouth of the carb.
Once there was no leak but after starting it leaked....and we had a small fire....not good at all.

So I adjusted the carbs to a level that they don't leak, but the bike will not hold rpm as it runs out of fuel.

What gives?
Plan to take them all back apart and see if something jumps out at me.

Also the stock jets are installed 100/38
Not sure what I should get for the stacks and drag pipes.
Ill order some brass ASAP.

Have you checked the overflow tubes aren't cracked?
 
Also, are the floats free moving on the pins?

My 400f does the same damn thing. I cant figure it out.
I think the valve intermittently sticks open somehow? Possibly contaminants in the fuel?

I swear every time I fill up with gas it is running just fine, no leaks, and then when i toss it on the center stand it starts leaking all over the damn place until I turn the fuel off. When I turn it back on it stops. I dont understand at all.

We had the same problem with a pair of CB77 Keihin carbs on a CB160 race bike and every time it turns out to be the gasket just touching the floats.  Sometimes it's OK and the next time it pisses fuel everywhere.  We tried genuine Honda rubber gaskets and keihin and they all cause the problem.  Fix was a very sharp Exacto knife to trim a little material off the inner faces of the gaskets.

Took a good look and can't see evidence that the float is rubbing on the bowl.
Kinda hard as I can't see inside the bowl when the bowl is on...lol

Will strip them down and see what's what.
Maybe it's just something stupid.
22mm isn't a misprint in the manual right?

Crappy cell phone pictures







And what's better then some finned covers for a bike that's not running?

Got some new brass.
Fishing lures were just to meet the min for free shipping.
Have 38/42 and 100/105/110/115 on hand to tune.
Also got new float seats to cure the original issue that caused the fire.




Rack of carbs to be used to replace the broken parts from the rack on the bike.



Bought a Morgan Carbtune.
Exchange rate is great so I had to have one



Is is the bushing in the carb rack that failed



Maybe over the winter when the head is off for a new head gasket it will get a big bore and these...



But for now it trying to figure out if I should keep the orange stacks or swap them for something else that matches better.

Dug up some charging parts.
Figured I would swap on in and "band-aid" the system for the rest of the season.



Over the winter ill build a proper harness and swap in a solid state rec/reg




Made a tail light bracket.
Nothing special, just some thing simple.




Also got an oil cooler adaptor.  It's for a 750, but I think it should be the same for the 550.
Need to find an actual cooler.
