To check the oil level in a Yamaha YZ 85, first ensure the bike is on a level surface and the engine is cool. Locate the oil fill cap, usually on the right side of the engine, and remove it. Use a dipstick or your finger to check the oil level; it should be within the designated range. If it's low, add the appropriate oil until it reaches the correct level, then replace the cap securely.

You can't chaeck the oil level in a newer 2stroke you have to just change the oil and put the right amount back in it.
this is directly from Yamaha i work at a dealership 5w oil is recommended 329cc or 90mm oil height
you have to remove the oil check bolt. its about half way up on the clutch cover and is just a regular bolt. remove it...if oil leaks out, the level is good. if no oil comes out, visually inspect it and see if you need to add more in...most likely you will. Fill the crankcase until oil leaks out of the hole where the oil check bolt was. At least this is how i do it for my 04 yz125..
Drain it and put the right amount back in it, it shoud say on the side cover right near the oil cap
use decent two-stroke oil, check the container, but 50 to 1 is good.
Want is the engine oil capacity for a 2000 Yamaha yz 250.
To change the oil on a 1996 Yamaha YZ 80 2-stroke, start by ensuring the bike is on a stable stand. Remove the drain plug from the bottom of the crankcase and allow the old oil to fully drain out. Replace the drain plug and refill the crankcase with fresh 2-stroke oil through the designated oil fill cap, using the recommended oil type for this bike. Finally, check the oil level to ensure it’s within the appropriate range before starting the bike.
A good way to tell is change your oil. When a head gasket blows you will have water in your oil or oil in your water system. Check these 2 areas for water and oil.
You need the mixture of gas and oil mixture for 2004 YZ 125 in the ratio 1:32.
the front fork oil leval is to be set at 130mm from the top of the fork (air gap)..with the fork spring out ..and the fork fully collapsed ....
No it wont due to the keyway location which knocks out the timing. The crank will fit into the 80cc engine but you will battle with the timing which will run the engine in reverse. The 85cc conrod and big end pin fits the 80cc crank
