it happened again
« on: April 16, 2011, 11:40:17 AM »
After replacing my sprocket shaft seal which solved my problem(or so I thought)Rode to work the other day,bike was running great,doing about 75 mph in 5th,dont know the RPM's cause I dont have a tach,And suddenly I lose power like I had to switch to reserve,but it was relatively sudden,like WAAAAAAAAAH-wrrrrrrrrrrrrrr,seemed to start running better,but I got to work and the rear of my bike is COVERED in oil. >:( :'(.What the F#*&!!So I get my truck go get it,pulled off my sprocket and the new seal failed at the shaft,There are no burrs on the shaft(I felt it before I installed the seal).
So,A.its a bad seal.
     B.Excessive crankcase pressure.
     C.Both
     D.Sell it and move on.(kidding)
Any guru's out there now why I would have excessive pressure?
All my breather tubes are intact.
Can it be an oil pump issue?

What sucks is,it fires right up EVERY time,idles great,runs great,I LOVE my bike,its part of me,I dont want to give up.
What I really want to do is pull the motor,Buy a refurbed one from Cycle X and be done with it.

I'd double check the vent tubes and their routing first. Not sure on the loss of power? Is the shaft blue where the seal failed? Maybe there is a bearing going away. Just a W.A G. never happened to mine.

have you tried to wobble the output shaft,i doubt a grabbing seal would slow you down,the power loss might be coincidental with say fuel blockage or whatever.

Yep, either excessive oil pressure for some reason or the crankcase vent tube is clogged.

Had the same thing happen on a friend's bike...The breather hose got plugged somehow, blew the front sprocket seal off, oil everywhere...Believe it or not, he blew out the hose with an air pipe, popped the seal back on with a large socket, no more problems.

Well,I pulled the oil tank and lines including breather hoses,cleaned the crap out of em,put a new main shaft seal,Filled with fresh oil,went for a ride down chuckanut and back,(the best 15 miles around here) so I notice a bit of smoke coming out of my left exhaust on take off,sigh.What now?At least it didnt spew oil all over the rear of my bike.I could have over filled it a bit,but would that make it smoke?New rings,valve seals,head gaskets,etc. less than 1500 miles ago and it has great compression,starts right up .Possibly residue in the oil tank burning off?
