What is the bike doing that caused you to post? Does it backfire? When does it backfire? Where are these little flames coming from? I wouldn't ride a bike where I could see little flames till I figured out the issue and stopped the flames as there seems to to be a safety issue here.
Bike runs fine but you think it is rich. Why do you think it is rich? Please try to rephrase the whole thing as I am missing the point here. Thanks.

First thing you do is get a manual.
Second thing you do is a complete tune up:
(A) clean/adjust points (assuming it's a 76-80 750 twin, 82-83 have electronic ignition).
(b) check/adjust ignition timing.
(C) check/adjust valve clearances.
(D)Replace spark plugs.
(E) check resistance on plug caps, coils, spark plug wires.
(F) check/replace air filter.
(G) check voltage at battery while bike is running at 3k rpm.
(H) check voltage at coils, ignition on, bike not running.
Do all the above and if it still has problems, then we'll talk about the carbs
Do it right the first time, or do it over and over and over while running in circles pulling your hair out, the choice is yours
My 79 70 twin starts on two kicks stone cold, half a kick warm, runs perfect, and I assembled it from a bunch of parts from different years/models of Kawasaki's.

when at idle it has a flames. nothing outrageous but talking to some friends at work they said it maybe rich. i have pod filters and a open exhaust . the backfiring is just a thought really i beleive its like a map gas torch sound when you light it . its the flames i believe . it runs good though. my inline four when i ran pods and a 4 intoone header i had to adjust carbs would not idle right .this one idles fine doesn't back fire when you give it gas and its an open exhaust. i will take pics tonight when i get off work and post so you can see exactly what i am talking about.

I ended up doing the circles and pulling hair method... but now my twins start with one kick too...
But I agree with George, in that I agree with steell...
Oh, and just replace the coil... you won't regret it... and while you're in the manual, set the float height... whoops we're not on carbs yet...
