My 2001 classic had gas in the crankcase. I have dropped the oil, changed filter and I am going to take her out for a short ride and check the oil afterwards. Anyhows from the little research that I have done it could be several reasons for the gas getting into the crankcase. First I will adjust the air fuel to get her running leaner. It's just he back jug that is fouled. I know this is a PITA from when I rejetted last fall and need to know if anyone can tell me where to get a tool that makes adjusting that screw under the carb easier.
And any tips on what causing the gas to get into the crank would be great. I know it's not the petcock checked that yesterday

There is only one way for gas to get into the oil and that is through a faulty fuel tap. Rear plug fouling is another sign.
Rebuilding can be hit and miss with most folks just replacing and being done with it.

What causes my plug to foul? And what do i to check the petcock? I checked it by disconnecting fuel line below the petcock and turned it to run and it did not leak. Did not drip gas in reserve either. What about float bowl height?

Float height can be an issue, but only when engine is running.
With engine off, the carb "may" drain a little fuel into the rear cylinder, but not much to worry about.
The carb would need a steady supply of fuel to continue to refill the bowl as it drained and that supply is from the faulty fuel tap. Then the crankcase starts to fill up.

You said the tap did not leak, but that was "today". What about the previous days and the days to come?

As others here can tell you - replace the tap and most of your problems will be over.

Fuel tap is leaking. I am considering buying a Pingle over the OEM. Has anyone done this and what is your opinion?

1. If you buy OEM, it is cheaper and still has auto shut off. It will probably outlast the bike.
2. In order to take advantage of your new fuel tap, you should also tear down, clean, inspect, replace any suspect parts, and adjust to Kawasaki specifications, the carb. Good chance it has never been done.
3. Check inside of tank for rust and other contamination.
4. Check condition of all rubber hoses, including cooling system.
