Well about a month ago I drained all the oil from sitting over winter, and then put in new Motul synthetic. After a few rides it was really low (forgot that the level drops once cycled through the engine), so I put more in. And I put just a tad too much, I think. When sitting cold or when I just start it up, the level sits right below the top line on the oil glass guage but after riding it's completely filled to the top. Is this too much (I feel like the strokes are longer and that in lower gears its harder for the bike to rev)? If so, has anyone here tried to siphon oil out? My friend said he heard of someone using a "siphon gun" but I have never heard of such a thing?
