Dear Harley Friends
Here is my problem! In October of 2005 I purchased a new 2006 Harley Ultra Classic from the dealer. Prior to taking delivery I had the dealer upgrade the engine to the 95CUI kit, which included the high flow heads, high compression pistons, 203 cam, Harley race Tuner kit, Stage I breather, and a set of Reinhardt True Duel exhausts. Other than the exhaust all parts were Harley made and installed. All work was performed by the dealer. I took delivery in early October and road the bike throughout the fall and occasionally during the winter, as we had a fairly mild winter here in the North East. The bike ran fine with no problems. The bike never sat for more than a month without being run and was kept in an attached garage, where the temp never got lower than 45 degrees. In mid March I called the dealer and arranged to bring the bike in for its first service. At this point I had put 1200 miles on the engine. The dealer asked if I wanted to use Syn 3 oil and I said yes. After the service I road the bike home and it sat for a few days, then I went for 250 mile ride and I noticed excessive blow-by coming from the air cleaner. So much oil would accumulate in the air cleaner housing that when the bike was parked it would literally pour out in a steady stream down the side of the engine, not mention the mess on me and the bike that was cause by the blowing oil. I checked the oil and discovered that in the course of going 250 miles the bike was already ½ quart low. I brought the bike back to the dealer immediately. After two weeks they said the problem was an oil pump that was out of alignment and they had road tested (50 miles) the bike and found no problem. I picked up the bike, road the six miles home and found no blow-by. The bike sat for two days. Then on the following Monday I took the bike out for another long ride, about 65 miles in to the ride I checked the air cleaner and there was oil leaking once again from the air cleaner housing. I turned around went back to the dealer and showed them the mess! In addition the blow-by was so bad it got on my rear break rotor and stopping became difficult. In addition I checked the oil and it was now down almost a full quart! The air temp during both rides never exceeded 60 degrees.
So what do you think is the cause of this excessive blow-buy coming from the air cleaner? I know that overfilling can cause this, but I checked the level according to the manual and it was not even close to being over full! I believe I broke the bike properly, keeping the RPM’s within a range of 1500 to 3000 never lugging or excessively racing the engine. I varied my speed and thought I had done everything correctly. Everything was fine until the first oil change, now it leaks like an Exxon Tanker? There is no smoke coming from the exhaust and other than the oil problem it runs extremely well? Do you think it could be rings, or a faulty oil pump, the Syn 3 oil instead of the regular oil, or something else? Please help; I have over $26,000 invested in this my third Harley. After reading your two letters I refuse to accept the fact that a bike I paid $26K for leaks like a piece of junk! Help!!!!
