That Dude's bike, VERY LEAN??????

[feelergaugephil]

"That Dude" has been round to my house a few times and we have been fixing it up. (1981 GSX 750, 16Valve)
It had 4 K/N type air filters, so we took them off and put the standard air filter on (NO air filter box, just air/paper filter pushed up against the intake rubber)
It has standard pipes and approx 20K on it.
Here's the problem, we have done plug checks after numerous miles and the plugs are extremely WHITE.
It has 117.5 main jets in the CV carbs.
The adjuster air intake screws have been set and different turns, wheather half a turn out or 3 turns out the plugs are still WHITE.
That is ALL the plugs.................
It runs a bit rough on idle but revs clean thru on opening the gas.
I checked all the tappets which were all within spec.
Any ideas? as he can't ride it too far with white plugs cos it might sieze..
HELP US OUT GUYS..........

The simple choice would be either RE-JET or STOCK AIRBOX and filter, running pods or just putting a paper filter up against the boots is just not going to cut it. It will still be lean, and any riding will just continually mess with the motor.

Well,
I have the stock air box but not the stock air FILTER box in which the filter sits. I've checked every avenue that I know of thus far and have not been able to find one. Would you know where I could find one? Would that help my leaning out problem?

And the pods went out in the trash weeks ago. They suck.

If your box takes a foam cylinder like mine does that is about 5 inches tall, you can use the foam filter replacements from some quads and snowmobiles, they will be tall enough to fit the box bottom to top and go around the plastic keeper.
