I understand a cdi swap isn't going to net me anything. I thought the sluggish performance when cold might be to a weak spark ( bad coil etc ).

What style jets do these stock carbs use? Any idea what the stock jetting might be?
I have a few jets laying around from a few assorted jet kits I did on my supermotos.

And I would have to disagree that spark doesn't make power. Better / hotter spark or more duration or in the case of aftermarket ignition systems such as msd mallory etc use multispark for cold starts etc.
While obviously the volume of fuel/air into a cylinder makes power the efficiency in which that fuel/air is burned is just as important.
And I also believe that stock volumetric efficiency for a good operating engine is around 85% if I'm not mistaken.
