No, It is contaminated with dirt.
Drain the oil and gas out of the crankcase and put oil back it should be OK
no, the oil is mixed with the gas before it goes in the carb, so there should never be oil sitting in the crankcase.
crankcase oil is the oil in the engine .some call it crankcase oil some call it engine oil
there is a problem with the PCV (positive crankcase ventilation) system. this system circulates crankcase air and oil particles in the air back into crankcase by pushing them back somewhere back through the intake. there is probably a problem with the PCV valve stuck open allowing too much oil to pass through it subsequently collecting on your air filter.
Yes. The oil drips into the crankcase via the oil filler location.
The foam is atomized oil. Crankcase oil flows with the freon.
Crankcase oil is engine oil , so yes
Yes, oil should be put in the crankcase on a 1989 Suzuki RM 250. The proper oil to use for this is a product made by Standard Oil called 80-90W Gear Oil.
Put the bike on its stand. Loosen and remove the oil fil plug on the right hand top side of the crankcase. Put a funnel into the hole. Put a large pan or container under the crankcase. Loosen and remove the oil drain plug from the bottom of the crankcase. The old oil will run out. Then, put the oil drain plug back in and tighten it. Finally, pout the correct amount of JASO MA or MA2 certified oil into the crankcase.

I have an 1980 Yamaha Enticer 250 (ET250D). Here's what the sticker under the hoods says...The oil capacity for the "Chain Case" is 15.21 oz (or 450 cc).If you are talking about the engine crankcase, there is no oil in the crankcase of a two-stroke engine. It is lubricated by the oil that is mixed into the gas.I am not sure what weight oil to use. The dealer told me to use Yamaha Chain Case Oil (but he didn't know the weight of the oil).Hope this helps!TK
The capacity is 0.75 litre, oil should be 10W40 for motorcycles
