Teds new project a CB500 K1 mostly version 0.5 circa 1972.
Oddjob:
Don’t drill unless you really need to. In alloy the metal is so soft you can normally just use the tap to enlarge the hole. I’ve done loads of M4 repairs in carbs and they’ve all lasted. Buy a kit off eBay
The insert is normally a few threads too long so cut a couple of threads off.
Trigger:
Just buy the correct length heli-coils ;)
Oddjob:
That's what's in the kit. Why spend money on others when you can just cut down the ones provided. ;)
McCabe-Thiele (Ted):
Petrol pipe & vent tubing arrived today so now have the carbs ready for fitting to the mainiolds - I will attach them to the bike and test for fuel bowl valve leaks.
I know they are only fuel vents but think I will slip some new short pipes in between the carb bank as the left one is a tad manky.
Bench synch done.

Oddjob:
Adjuster screws seem high to me Ted, you may find hanging idle with them that high. Try winding them all right down and then bench sync with a 2mm drill instead of a 3mm one, wind the idle adjusting thumb screw right out so it's not touching the lifter arm.
Also open the choke and check all the flaps are level when the chokes fully open.
Pic from the front as well please, I'd like to see how that ceramic chrome effect bracket looks when all the carbs are fitted.
