hey guys - I was doing some minor maintainance on the virago last night and I realised that my engine oil window is clear...... now last time I remembered I saw a golden - substantial amount of oil in that window that was just under the recomended line.... but now it's clear... so in my understanding.... there's nothing there??? how is that possible?? there are no leaks or anything on the floor and yes - I stood the bike upright for a coupla minutes plus I warmed it up.... and nothing???? I will be changing the oil anyways - but how is this possible??? or was not patient enough to stick around till the oil finally made an appearance in the window?
