Yes, the arrow should be facing forward. It is possible to find a small amount of oil in the crank. If the previous owner were using an odd oil/gas ratio like 32gas/3oil instead of the normal 32/1. The proper mix is four ounces two stroke engine oil to one gallon of gas. The more oil in the gas, the more oil in the crank. This odd mix usually happens if the owner doesn't know the proper mix, guesses the mix at the pump or just doesn't care what goes in so long as the bike still runs.
If you found condensation on the piston then the crank would have likely received the same blessing. Check the crank bearings.
Hold the flywheel in your hand. Lift it up and down then move it left and right. Any movement or is it rock solid? If movement then you will need to take the gearbox apart and install new crank bearings and seals. Put the old cylinder and piston back in place without the head for a moment. Put the bike on blocks so that the rear wheel is free to turn. Have someone rotate the rear wheel while you work the clutch and gears. If the gears don't want to shift smoothly then plan on installing a new shift fork or two. Now would be a good time for a new sprocket shaft bearing and seal as well. Don't forget a new foot shift shaft seal.
While you are doing repairs, de-carbon the head and cylinder. Run the piston down and check the exhaust port. Over the years carbon may have built up in the port and plugged it nearly closed. It should be about the size of the intake port. Remove the buildup to allow the engine to breathe.
Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ). Install an in-line fuel filter. Install a new stock NGK spark plug.
Drain and clean the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.
I know this answer is more info than you asked for but I don't want you to have to go into the case more than once. Congratulations, you just rebuilt the entire engine.
Please rate this answer. Thanks Paulette!

im pretty sure that the bike is a all in one menin that oil in tranny is same that flows in motor
SOURCE: KX60 2001,losing oil from crank casing and won't start.
hi mate take it to a descent welder who can weld aluminium and when welded fill it back up with light gear oil and also the bike will start with no oil but if ran too long the gearbox will seize and will cost you a engine rebuild normally 300 pounds ++ so get it sorted asap good luck
SOURCE: bought a used 88 cr250 and like and idiot i didnt
sounds like you need a clutch. Yes the friction plates should move a bit when you pull your clutch lever in that is how the clutch works what oil are you running in you tranny and have you tried adjusting the clutch cable? When you had your clutch apart what did the friction plates look like was there much meat left on them?
Testimonial: "thanks for the info...thats what i thought, just didnt want to hang parts and hope"
