Default Re: Opti2 and fuel filter darkness

Thanks guys. I guess it could be dirt in the tank or maybe an o-ring is breaking down, but it appears "oily" and that tank was cleaned out.

All fuel is mixed in a gas can and well shaken before going into the bike.

Nothing seized up yet so I assume the slippery good stuff is getting through the filter to the engine, but it does look odd.
