seepage

I have a bit of seepage on a mystery cover on the S10

According to someone at
http://www.yamahasupertenere.com/index.php?topic=9081 the cover is a
blanking plate for an alternative location for an oil filter. I guess
Yamaha have other applications in mind for the engine where the filter
needs to be located differently.

Apparently there is an O-ring behind the cover so should be a simple fix at
the next oil change.

Thats a bit odd. You shouldnt really have seepage at all. Will keep an eye on mine

( good to see my downpipes are exactly the same as yours )
