Top end noise from the word go, progressively got worse, then bottom end noise started around 5500 miles, at 6400 miles oil coming out of bottom of front jug where it meets the crankcase. Service mgr (at a large dealership) told me this is becoming a problem on the 103 motors...they are having a problem on some of the bikes...oil coolers are slowing down the flow of oil to the top end, and consequently burning up. He told me they are rebuilding these and taking the oil coolers completely off and is fixing the flow problems.
