right side crank case
To check most transmissions on Honda motor cycles you check engine oil. They have a liquid clutch that are in the crank case oil.
There is no oil in the crank case,,you use mixed gas and oil that's what lubes the crank bearings and piston rings.
What oil
The Crank Case is dirty. Use a good Crank Case cleaner to solve problem like Motor Medic Motor Flush. Warm engine 5 minutes and let clean out for 5 to 7 minutes. Then drain and use fresh oil.
PW 80 is a 2 stroke. It does not have oil in the crank case. I think you mean transmission oil. I use 10w40 engine oil in mine and it works great.
That depends on your moped. Most mopeds madein the 80's are two stroke engines. Which do not use oil in the crank case. the oil is mixed in with the fuel.
your crank case does not take oil at all. your transmission however will take usually 1 to 1.5 quarts of approved transmission oil.
By removing the plug at the bottom of the oil pan and letting the oil out.
It is inside the crank-case.
The 750 STS Kawasaki Jetski uses 2 cycle engine oil. 2 cycle engine oil is specifically made for use in jetskis.
It injects oil into the fuel/air mix.
