Hey rb550four!
Thanks for the great thought starter/advice. The "grave" wasn't too deep, but there are lots of little parts missing from some previous owner who must have had project A.D.D or something.
I was able to slap the right side exhaust on and bolt it up no problem, but regardless of how loose the left side is and how much I fiddle, I've come to the conclusion that it's not gonna fit without "relocating" the kickstand mounts. The pipes come under the frame and split with ALMOST enough room to get the stands to split the pipes, but not quite.
To keep the project moving forward while I source the right exhaust, I decided to tackle the carbs next. I've finally given in and ordered an ultrasonic cleaner but in the mean time I began disassembly and evaluation. I was surprised to find metal "diaphragms" where other Honda's have had rubber in the carbs! A very interesting design, however I'm missing a slide return spring... I also noticed that the pilot and secondary jet don't have screwdriver slots to remove the jets. Anyone know how to get those out? Or maybe I should just leave them in and clean it that way?
In my excitement to disassemble, I also removed the choke plates, however when trying to screw the old screws back in, it appears the cut and flaring of the screws will require me to get new screws or risk cross threading the brass mounting shaft badly. Annoying, but not the end of the world, It appears in retrospect that it is necessary though to allow me to replace O-rings on those little "pipes" between carbs.
Anyone know of a good way to make their own or buy new T fittings for fuel lines? The ones here are 100% shot.
Also, I found this brass piece in the bag of miss-matched carb parts that is clearly broken off in the threads. Anyone know what it's for? I couldn't find any threaded hole with the other half in it.
