mysteriously im losing oil

[mvaughn556]

check this out. im losing oil like crazy, about a half a quart every 90 miles. this is the crazy part, im positive that there is no oil leaks, im clean all over. im sure im not burning oil, intake and air box is clean, muffler as well. haven't lost any performance or no code error. oil level check procedure was done correctly.
no im here scratching my head and thinking to myself WTF?

that rpm do you ride at and what are the temps?

 

[rchuff]

did you look at the back of the rear cylinder and fan area, known to leak their and fan blows it out leaving oil all over fan.

then you must be consuming/burning oil meaning worn rings.

Yessir agreed

ok just finished with the compression test. rear cylinder is reading 195+psi and front is reading 220+psi. also taped paper all around the motor and went for a ride to catch and find a leak. nothing was found i was sure it was my rings or valve seals. WTF!

how much oil are you losing? these bikes lose oil through the crankcase breathers...it basically turns into a vapor and gets put right back into the intake on stock configuration. most people do a breather reroute with a filter.

 

[theMelvster6]

sorry wrong area...but i would assume it still has a breather.

On the old vintage I-4 jap bikes it wasn't uncommon to eat half a quart every 2-3 thous. Just check and refill. Maybe every 90 miles is unacceptable though[mad]

 

[mvaughn556]

fords does that as well but ive put 7k miles without any issues till now but i my have an idea i'll get back once i conduct an experiment

found out i wasn't losing oil but engine was hiding it. I'm doing my first valve check. i did a hot check and was not remonstrating on the dip stick so that means im low. but after measuring the oil i drained found out i have 4 quarts. one quart over im using amsoil thinking i have a clogged up oil jet some were in the motor
