alright so from my precious thread the "I got screwed", I replaced my oring in the pipe that connects the water pump to the radiator and no more leaking! but now I went for about a 3-4 mile ride and come back put it in the garage and see oil dripping, its a very slow drip its not from the drain bolt, somewhere near the shift lever is there any common seals or gaskets that go out here that will cause oil to drip?

its a 98 wr400 btw

There's a crankcase breather hose that dumps in that area. It's normal for it to drip a bit.

The seal behind the front sprocket tends to go bad. Happened to my bike, or it could be coming from the seal on the shifter. Try to wipe it away any oil around there and start it up and trace the oil to the source.

Thats either the head gasket leaking or more commonly the plug right above the head pipe.

Based on your first post, I'd check close around the countershaft sprocket - pretty common to get leaks there. Then maybe at the shift lever. If its the countershaft seal, not too hard if you take your time. Do a search sure to replace the seal AND the collar and o-ring that run inside the seal. Good luck!
