I assembled the carbs back together id say about 7 times on the bench for my CB500K0. I have a spare set of carbs to reference and another CB500K0 to look at as well. I learned that carburator inside and out and there really is only one way to put those carbs back together on the rack as I certainly found out. A bunch of cool engineering to get everything to line up etc...
I also got my rebuilt and painted caliper with new OEM piston on my CB500K0 cafe bike with my aftermarket master cylinder after I was having a moment of stupidiy wondering why I couldnt get any pressure built up in the system as I didnt have the cap screwed down and sealed. I also rebuilt my other CB500's brake caliper last weekend as well.
I also had another bank of carbs pulled and redid the float heights after a cleaning from ethanol in the system clogged stuff up, mounted them on my other cb500k and had them weaping like crazy and was very frustrated. I let it drain out then start the bike with the fuel bowls full of fuel and the problem corrected itself. I had put some kroil in the float jets and blew air into the gas line and let the floats seat a few times to get them nice and lubed up and seat properly which did help a lot, then sealed it up and went along as I stated above.
I also looked at my CB350twin and said hello... If I didnt have to get all oily to do your timing I would pay attention to you right now. I did add a little marine stabil to the gas though.
I also laid a little clear on the red OEM kill switch that I am rebuilding.
I also looked at the non cafe CB500K's rear brake that is out of adjustment and it techincally works now but I need to do some research and have another go at getting her working right.
I didnt drink one beer but did a little chewing tobacco... The girlfriend also wasnt upset that I was working all day long and was very understanding. So I believe it was a success.
