You are checking oil on a cold engine leaning away from you, you are filling it to 3/4 still leaning away from you, you ride and now that 3/4 is closer to full with hot oil. Oil gets blown out the breather, you park the bike, check it next week and see that it is below 3/4. My internet forum guess is that you are overfilling the oil tank, jus sayin.

Wouldn't been seen on the air filter? Btw even with a WARM to HOT motor its still says it low. I checked it after when I rode it a few miles. It still says low.

 

Do a compression test

 

What is normal for an EVO?

 

No mystery here...if the primary is not overfull, only 2 places it could go...on the ground, or out the tailpipe...if there is not a drop on the floor after a long ride, burning it is the most likely culprit.

 

I've got to agree. But the sumping issue does make things difficult to check. I only check the oil at the end of the ride, immediately after shutting off the engine. Otherwise it's just way too inaccurate.

 

Let's see, it's not leaking but it's using 1/2 to a quart every 250-500 miles? No mystery.... Sounds like a top end in his very near future.

 

What do your plugs look like?

 

Inspect the spark plugs, if it aint leaking on the ground, the plugs will have signs.
