Oil leak: another common issue

again while my motor is out I thought I'd post some decent pics of another common issue: oil leak in the front cylinder

if the front of your engine is covered in oil from the exhaust down this could be why, in the pic below is the front of the motor, you see a little tube sticking out with a tiny weep hole directly below it. this is probably where the oil is coming from.


closer pic



It is a simple fix, you just need to replace the orings in your spark plug wells. pictuerd below



To remove this you need to remove your rear axle nut to use as a tool



The part numbers for the orings can be found on most sites under the "cylinder head covers" diagram but here are cheapcycleparts number 92055-1255 and 92055-1272
as always, hope this helps!

When I was younger I was afraid I'd die riding. Now that I'm old and falling apart, I'm afraid I won't.

I thought it was a sticky, oh well. I did this write up long after I replaced my orings so if anyone takes their spark plug wells out please add some pics of the orings on the wells! I didnt want to go through the trouble although it is pretty simple to remove my axle nut again and pull my wells out for the write up.
