No issue. Was just out taking care of some farm needs.
A leak down test is a great tool to understand your engine. Youtube and internet is a great resource. and here as well I may add. lol
The same adapters are used, but you use compressed air and inject the cylinders with air or Nitrogen. You watch the gauges to see any leakage. generally, a leaky valve question is answered using this method, although rings can also be troubleshot using this method. The oil on the rings as mentioned above will rule that issue/concern out for that troubleshoot.
The leak down method is my preferred method over compression testing for troubleshooting or testing even though compression tests do have their place.

Alright man thanks. I ordered a repair manual,so I can have it to refer to. Will the indent on the valve float be something you can see with your eyes? And what would you suggest to clean the carbs?

I disassemble the carbs, soak them in a carb cleaner overnight, then use compressed air to blow them out.
You can see or feel a ring/indent normally on the valve. edit: on a worn valve that is

Do you feel comfortable doing mechanical work? Do you have any friends or acquaintances who are motorcycle enthusiasts and who know how to work on them? Any decent motorcycle oil should be good to start with. I use Shell Rotella T 15-40 (which is actually made for diesel trucks, but is quite widely used in the motorcycle world). It's inexpensive so I change it often. Inspect and smell the used oil coming out. Is it old and contaminated? Smell like gasoline?
See if you can find the service manual for your bike, or a similar model, online. That should help. Look around youtube for motorcycle carburetor cleaning instructions. There is literally a plethora of good stuff on youtube. Do you have the tools and know how to do a compression test? Look that up too. How is the gas? Fresh? Stink terribly? Is it full or near empty? Remove the gas tank, swish it around and dump it into a bucket to look for rust flakes and other crud. Shine a flashlight in and inspect it. How are the rubber components (fuel lines, vent lines, carburetor boots)? Replace anything cracked and old.
