Leaking oil!

[Guest]

So I've been doing a bunch of stuff to my. 78 gs 750.. Changed the oil and filter, change intake seals, rebuilt the carb properly(orings, new bigger jets, cleaned it up).. About to check for valve clearances.. I took the bike on a test ride around the block and it was running away better! But now it has a new oil leak.. It's not the oil pan, drain plug or that area with the oil window.. Is there other gaskets that are common to leak oil?

There are several places that can develop leaks. Can you give a general area, i.e left, right, front, ect.

It'll help us if we know what model of bike you ride.

1978 GS750e.. That's what it says on the neck of the frame.

Check the usual suspects: cam chain tensioner, oil pressure switch and starter motor O-ring to block. They all drain out of the hole/tube under the starter motor.

Clutch pushrod seal, countershaft seal are both common leaks, as is the stator over gasket and the cylinder base gasket.

Left side: In addition to those mentioned...excess chain oil or missing oil separation screens in the cam cover causing oil to be blown out the cam cover vent tube.

Shift shaft seal.

It's also very easy to pinch the oil filter cover o-ring when you install it.
