filled the oil up on my bike a few days ago, nothing different to what i usually do.
left the bike overnight in the garage and when i came to it in the morning i had a small stain on the floor. oil leaking.

its not a noticable leak however, only ever get a small puddle when i leave it overnight for 10 hours or so. so i cant even tell where its coming from.

note, this has only started since i filled it up about a week ago now.

help appreciated.
leigh.

Hi ,a trick I use to find difficult sources of leaking is to cover the engine in talcum powder when clean and then the track of the oil will be revealed

Perhaps you overfilled it a little?

Go for a ride and some of the excess will be blown out of the crankcase breather, down the breather hose and youll get a little drip.

If you've just one an oil change, there's two very obvious areas to check.

Is the sump plug leaking? Did you use a new sealing washer? Did you cross thread it? Torqued it up correctly, under or over tightened it?

Is the oil leaking from the filter? Did you clean the area where it fits? Did you smear oil on the rubber o ring to stop it sticking and being damaged? Again, how tight did you pu it on? Should be done as tight as you can possibly get it BY HAND. That is with your bare hands, no tools. If your really anal, do it with a torque wrench to the specified torque, no tighter!

Not trying to overcomplicate it, just covering all bases.

Hope that helps! Smile

EDIT: Also, a small puddle from being left overnight is a pretty major oil leak in my opinion, next step would be having it piddle out before your eyes...

A single drip in a day is the biggest leak I'd be "comfortable" with, and even then I'd look to sort it asap.
