valve guide and guide seats
Iam one of the ones that asks about oil all the time. I have finally got the attention of the Harley tech about the oil loss. He thinks it may be passing through the oil guides seats into the primary. He said he would drain the primary to see if there is more fluid than normal. If it is true what should be my actions toward dealership since the bike only has 4500 miles on it. It is under warrenty but once you take the heads off to start digging around that is not good for a customers view.

If it was getting past the guides or the seats, your engine would smoke.
I don't know how it could get into the primary unless there is some leakage through the bottom end (think compensator area). If your H-D tech thinks it's from the guides or valve seats, you need a new tech.

I have been wrenching a long time and if the guides were bad you would have blue smoke on start-up with a cold engine.If you do not have that,I would think there is no valve guide problem.I think a trip to a second dealer for a skilled opinion might be in order!

Loss of oil from leaky valve guide seals can almost always be seen from the exhaust pipe(s), but only during decel. With the bike on the jiffy, rev the motor up high and then snap the throttle closed. As the motor RPMs wind down you should see wisps of smoke from one or both pipes if that's the problem.

Half a quart to a quart every 800-1000 miles. I don't understand all the inner workings of the motor. I've had to add 1 1/2 quarts in the last 2k miles. If it's not smoking or leaking I have no clue adn I guess neither does the Harley tech of 23 years.

Did you say what kind of bike you have?
My '05 RK had the dreaded vavle stem seal problem. It smoked on decel and used quite a bit of oil. It got to the point carbon kept the valve from completely closing.
I gotta agree with everyone else, I don't see how oil is getting past the seal and guide into the primary.
