Anybody....I have an 02 Roadstar...108" big bore kit, Barons BAK, Bub Jug Huggers, 31 tooth pulley, Dyna3000 set at 32b and 6 degrees retard, barons ported intake manifold....bike runs awsome....lots of power. About 4 weeks ago my oil level was at the half way mark on the dipstick....I went for a 150 mile ride one day and a quick 40 mile ride the next day....after the second day I checked my oil after about an hour of letting the bike sit and the level was just barely on the very tip of the dipstick. I put maybe 1/2 a quart in and the leve was back up to 1/2 on the dipstick again....the next ride I went on was about 50-60 miles and the level was at 1/2 still....I went on one more ride and checked the oil and the oil was back down just below the tip of the dipstick. My front pipe is darker than my rear pipe almost as if it is burning richer than my rear. My buddies tell me that once in a while when I get on the throttle that I have a puff of black smoke and then they won't see it for a while. I don't have any blue smoke like I'm burning oil or anything of that nature. I started my bike up the other day in the garage, let it warm up to normal operating temp and cracked the throttle a few times and had some black smoke come out of the front pipe....seems almost like it is carboned up. My rear plugs were dark brown with little carbon, and my front left plug had what looked like oil on the threads (maybe WD-40 from installing the plugs but not sure) and was very carboned up, the front right plug didn't have the so called oil on the threads and was pretty carboned up. Would anybody have a good explanation as to what is going on? Any advice or info is greatly appreciated. Thanks in advance.
