Oil blow by through breather

It could be a few things, It happened to me on my 2001 Ultra on a trip and it turned out it was the oil pump alignment. It could also be your umbrella valves but that wasn't my problem. I blew out a quart of oil in less than 600 miles. If it is the oil pump you need to re-align it. I went to ebay to find the tools, they are two tapered dowels about 2 inches long. First you need to remove your pipes and cam cover. Once that is off you will see your cam plate and the 2 gears. Release the tension on the tension arm, remove gears. You loosen all 4 bolts from the oil pump removing 2 opposite corner bolts completely. You then put in the tapered tool that re-aligns the oil pump. Torque the remaining 2 bolts and then remove the tapered tools and reinstall the last 2 bolts. Put it all back together and your done. I never had a problem again once I did this. Quick tip, make sure that the marks on the gears line up perfectly. If it's off one tooth it will throw and error code.

must be somewhat common, some oil. when I took my bike in to have the new jiffy stand bracket put on, of course they checked the tires, brake pads, did a real complete check over of the bike in the service drive. before he was done he took his fingers and put them behind the breather cover and slid them, (like a lady looking for dust on furniture), pulled his fingers out and luckily they were clean..his only comment was...bike is great shape...(hell, it ought to be, it's only 9 months old) so my dealer checks the blowby on all bikes that come in.

On my '04 ultra, I was getting a lot of oil dripping and it turned out to be the breather hoses were dry and cracked. Instead of the oil mist getting getting sucked thru the air filter, it was dripping off the cracked hoses. 20 minutes and about $2.00 for replacement hoses and problem solved.

last year comming back from sturgis I went into a " jiffy lube" type place before leaving town for an oil change. I figured they do so many that week they should know what they are doing.
WRONG!
The kid put too much oil in and for the long ride home, I couldn't figure out where and why i was getting oil on my bike and chaps.
My wife then told me she saw him put 5 full quarts in, which explained the situation.
At least my chaps won't rust for a while

my bike will only do it when I am riding at 75 to 80 mph.... I finally just bought a stainless line and remove the hose going to the backing plate and plugged it and ran the stainless line around the back and dropped it between the trans and engine on the primary side. I have not had any drops on the shop floor since. I like it better than drawing oil into the intake with the suction. I use to run the oil down to the add mark, didn't like doing that during the summer heat, now I run the oil to the full mark.
