cb400f - carb sync
Bryanj:
Dont just set at tickover but check at about 3000 rpm as well
blackeagles:
thanks for the info.
the gauges arrived but i'm a bit busy at the moment so will try later.
still don't understand why it running sooo rich. i know i'm only looking at it after it's ticked over for 5 or 10 mins with the screw out 2 turns turns its so black i can wipe the soot off with my finger - along with acrid fumes! it seems to prefer at least 2 3/4 turns out with little fumes and any more and i recon the needle will fall out. i did try to set the floats at 21mm and the slow running jet looked ok (but who knows) anyway lets see how it is after the sync.
Greg65:
Just a thought. As one part affects another what state is the air filter in? If it’s partially blocked it will create a greater vacuum and therefore more fuel will be pulled from the carbs. Good luck.
Lobo:
... an aside, I phaffed & farted so much balancing my ‘750 carbs (hot summer’s day) and had a coil fail on the next ride out. Coincidence maybe, but looking back the engine got overly warm...shoulda perhaps had a fan across it.

Cheap household fan and all doors wide open !
