Hi,
disclaimer: I am new to this, but mechanically inclined and have read the carb guide.
My bike is a 78 SE, got it completely stock except a Boyer ignition and it still mostly is. The bike had been sitting for some years but started well enough, although it was evident the carbs needed a good cleaning.
I took the opportunity and moved to UNI pods, mostly for the convenience of taking the carbs in-out as I knew I'd be doing this a lot. I now have the chinese puzzle motion down with respect to pulling the carbs, takes 5 minutes from bike to bench tops.
In any case, cleaned the carbs, re-jetted to 1 size up on pilots and mains, new o-rings and gaskets, and now the bike runs nicely, except for idle: it would site there at 1.2k, then if a red light took too long it would go up to 1.5k, 2k and stay there. Bit puzzling until one day I forgot to move the petcock from prime to on and saw the carbs leaking.
Float valves: with new ones and float height to 24mm and now idle is constant, pulls off idle fine and the throttle action seems perfect (to me...) across the whole RPM range.
Just wanted to share in case this could help someone, this specific symptom did not exactly yield many search results here when I googled.
Cheers
