I have been a bit busy w/ football season but managed to ride a bit on Friday.
I changed plug wires.
I still have an old [it might be THEE old] battery

Problem[s]:
Bike seems to stall at low throttle deceleration

It also seems to pop a bit

It seems to stumble a bit coming off of idle on acceleration

It was suggested that I have an air leak in the intake [seals?]

I hate it when this thing isn't running right.

I finally got a moment to change the intake seals. While I was at it, I installed a #45 lo-speed jet, made sure I had 2 1/2 turns on the idle jet too.

The pops and stalling are gone, just as was suggested.

I bought two jets yesterday and they were both stamped, 45 and 48.
[I went with the 45]

The jet I pulled out of the carb had no size number stamped on it.

Does anyone know what size jet that might be?

Do the stampings refer to drill bit sizes?

Stock low speed is probably 42.

The Keihin CV cough is cured by raising the needle ... The cough is caused by a lean condition as you move from the low speed jet area ...

Seems like all is good.
These conditions started abruptly, after 4 years of riding. I am hoping it was intake seals.
I have idle screw set at 2 1/2 turns. It was at about 1 3/4.
I guess I will try to tune the idle when I get a chance

If you do not have a FAN you should replace the INTAKE SEALS every 2 years ...

This stops the MYSTERIOUS CARB. PROBLEMS ...
