Oil reading erratic, now too full?!

300 miles ago I performed the 100 mile break in oil change, putting in 3 quarts of Mobil 1 10w-40 motorcycle oil. All was great until I checked the oil a few weeks ago and it was reading half way between low and full. To me this meant it was low so I added about half a quart, putting it up to full. I ran it for 30-40 miles more and checked it again. Now it was below the low mark?! I added another half a quart, putting it half way between low and full mark. I made an appt. at the dealership to have it checked out since it was under warranty. Before bringing it in, I checked it again and and now it was touch over the full mark?!

The dealership service dept looked it over and said it was actually overfilled, there were no signs of oil consumption or leaks. The tech said I shouldnt have added oil the first time because anywhere in between low and full on the dipstick is good. As for the second time when it was really low, the only thing I can think is it had just come off the trailer and was hauled about 40 miles. Maybe this effected the oil distribution in the crankcase/shared sump/torque converter? Has anyone ever had an experience akin to this? For the record, no I was not screwing in the dipstick.

Also the tech told me the only times he has seen people have oil issues is when using a synthetic because the engine is designed to run off conventional and synthetic has a different lubricity which can give you funky dip stick readings. To me this sounds like he was trying to get me to buy Honda GN4 oil.

The engine is a semi dry sump design so the oil check procedure has to be followed to get the most accurate reading (it still can fluctuate some). The 700 pioneer can hold up to 4 quarts of oil and 8 always run them overfilled to help with cold starts and steep inclines.

With a cold motor start it.and let it idle for about 3 minutes, shut it down and let it set a few minutes and then check the oil. If you check it during a ride or if you give it throttle warming 8t up and can give an inaccurate reading.
