What he said. I have weak spark on one cylinder on my bike and I
experience this exact problem. I've even been known to carry a spare
plug and a socket and a ratchet with me for roadside repairs. If your
plugs come out black, either you're running wayyy too rich for some
reason or you have an ignition issue (gap too big? plug temperature
rating too cool? resistor plug instead of non-resistor? wire shorting
to ground? coil bad?).

Do you really think they gum up in a single day? It ran fine one day,
and didn't the next.

You're saying it ran great one day but the next
day, when you opened the throttle it would bog
and die ? And the behavior had changed
overnight ?
CV carbs occasionally need a new diaphragm.
Could be that I guess, but I'm confused by your
statement that it ran great the first day.

A google user I see...........
You are known by the company you keep!
Does the bike have a choke?
Do you know how to use it?
