First, was it running when you pulled the stick? that will do it.

Not running? then did you put the filter on the right way?

If you made it past that, then is there a case breather that is plugged, or takes awhile to vent because it's dirty or full of oil?

Check that all is correct and clean and see what happens, probably didn't hurt anything, didn't run long it sounds

no not running when i pulled the stick, wasnt off for long though. about 90% sure i put the oil filter on the same way the old one came off. Not sure what a "Case Breather" is. =(

Breather is the pipe on the top of the motor. You will see a black pipe that comes out the top of the motor (beneath the fuel tank ) . Its a pipe that allows the motor to breathe. Comes of easily. Take it off, run a piece of wire through it tied to a piece of rope. Pull the rope through, make a knot in the rope and then pull the knot through the pipe. Should clean her right up!

your bike is a dry sump, after the motor warms up it stays in the frame. dip stick is on the top of where the oil is and the drain plug is on the bottom in the front. if you did not pull that one then it sounds like you have to much oil after the change. the oil filter will only go in the correct way.

Soo poking around on the internet, Do these bikes have a Frame drain bolt also?

At the bottom of the square frame tube that the dip stick goes into. It is at the front/forward side of the frame if I recall correctly.

I had an '04. It was a great bike.

OMG....

Yes, and the frame being the oil tank, that's where almost all the oil is unless the bike's been standing for a few days. You took a bike that has a 1.2L capacity, drained probably less than 300cc, and added 1.2L. No wonder oil came out the top :eek:

Here's some info:

Well glad you figured it out. I bet you have downloaded the service manual by now and have read it from cover to cover... I'm sure your no the first one to have this happen, just be happy that you didn't do serious damage. Just out of curiosity, didn't you think it was strange you were adding a hell of a lo more oil than you were draining?

I have an '04 and yes there is a frame drain bolt in front. It is right above where the lower frame tubes are welded to the main frame section. This must be drained as well as the engine case. Total oil capacity with a filter change is 1.27 qts. When checking oil, make sure engine is only warmed for about 3 min and the shut off before you pull the dipstick. If the engine is too hot, it will also overflow out the dipstick hole.
