Quick question as this is my first non dirt bike and I have not really ridden until a month and a half ago. I go the bike on 5/23/11 an 06 Vulcan 900 classic with 4300 miles on it. Didn't get mi license until the middle of July, and since then have put about 2300 miles on her. I bought it from a dealership and was told that it had been completely serviced prior to my picking it up ( I specifically asked about the oil change). Today on the way to work it seemed to be running a bit off a little rough and the power did not seem right. Got to work nd checked the oil ( it was low just barley in the sight glass). ran to the dealer where i work and bought a quart and filled her up to just under the upper line on the sight glass. Total it took a little over 3/4 of a quart, to mee this seems to be a lot. Or am I off and just have to monitor the level a little better.
