I have a primary leak on my '03 Ultra that is driving me nuts too! Sounds like it could be expensive according to the dealer. I'm keeping an eye on the fluids all the time now.My girlfriend makes fun of me for keeping my bike so clean. I rode 700 miles this weekend and cleaned and waxed it twice. She does not get it, but thats ok. I do have a primary leak thats driving me nuts, but it's August and I'm not gonna tear down anything until riding season is over. I keep a close eye on oil level and wipe down the rear tire. I just hope it's an easy fix.
