Niko, you've inspired me to take the plunge and rewire a chopper using the m-unit. Looks like a great piece of kit...where did you source the wiring supplies?
I bought a wiring kit motogadget supply, was about £40

Running one myself, I'd definitely recommend a hondaman transistor ignition.
The ignition retains the points but uses them as a switch to trigger the ignition. As they are no longer carrying the full voltage, no more arcing of the points so they don't wear out. Dwell and timing is kept stock (alot of elec ignitions produce a very short spark)
Should the ignition box ever fail, simply reconnect your points at the side of the road and your no longer broken down.
Couldn't be happier with mine, bike is no longer cold blooded on start up and idles alot smoother.

That is pricey, those CMA wheels look good though

Yeah 110 main should be good for pods, needle clip should be middle position too

Yeah i'm sure Seabeowner is right, id go for the 58.5 550 pistons and overbore as mileage requires. Using the 61.5 600cc pistons leaves the cylinder liners awfully thin, so overboring isnt possible. Another option is machine down some 750 pistons "gentlemens express" style to give 590cc http://www.chinonthetank.com/2012/05/cb550-the-gentlemans-express/

Im not sure there is a problem, these engines do run hot, as all air cooled engines do.

2nd from the top is stock, 3rd should be good, 4th will most likely be too rich, unless the engine is hopped up a bit

remove the floats and submerge them in water, if there is a crack in the float, it may be filling with petrol and sinking

valve clearences too tight?
disconnect the hose from the crankcase breather ontop of the engine and try that. I had a 550 taht would build up crankcase pressure and die after a short ride

the 500 carbs are fine on the 550, they were just jetted differently from the factory
If you dont have the airbox to put back on, your just going to have to work with what youve got, either way youll definiely need to drop the needle clip to the 3rd slot to richen up the mid range, if youve already got 110 and 115 main jets throw either of them in, 115 if your exhaust is particuarly open and see how it pulls with wide open throttle
I have seen aftermarket pilot jets that are alot shorter than the stock keihin jets, do your pilot jets have a logo on them? oem keihin is always better. That may be causing your idling issue.
These adjustments need to be made to run right with your set up anyway, regardless of the idle being the main concern right now.
what rpm are you idling the bike at?
Also what position is the choke lever in when your running it, it wouldnt be the first time the position of choke on and off was confused (the thump tab on the choke lever becoming horizontal is full choke)

The carbs aren't the dreaded PD carbs, good news there! there is a picture of them on the first page, they are either 069a, 022a or 627b(cb500)
You should be okay with the 40 pilots at idle but 100 definitely isn't enough of an increase in the main jet, and without the needle clip moved to the 3rd it just won't cruise right, constant adjustments and increases in the throttle will be needed to maintain speed, ask me how I know.
Your right, in with the screw richens the mixture
