Today upon checking the oil level on my Ryker 600, after pulling and replacing the dipstick, I had to clean up a big spill under the bike. Probably at least 3 ounces of oil. The oil level reads very much overfilled, but it was last changed 3 mos. ago by my dealer. I checked the level twice and got two puddles of oil on the ground. I'm baffled since I have no idea what the oil system internals are like. No leaks ever before and not now as long as I leave the dipstick alone. Any ideas?
