The rattling noise may be from a loose or bad exhaust ring, when the bike is cold grab the exhaust pipes up by the head and try to move them sideways , if you find any movement try to tighten down the flange , if that dosn't help replace the rings

Well I changed the spark plugs today.

When I took out the old one cylinder #10) there was oil on it, but not the others.

Started up that bike and smoke came out of the left hand exhaust (bike still has the original exhaust). When I roll the throttle even MORE smoke comes out.

So what might this be?
