oil sight glass almost impossible to gauge

[darrsi]

When i first bought my bike i took it out for a blast and on returning noticed an oil leak from around the cam chain tensioner area.
I thought i'd change the oil anyway for peace of mind, and the previous owner had put 4 litres of oil in the engine instead of around 2.5 litres.  :eek


I wasn't impressed.......


All this talk about oil, i think i'll do something constructive today and go and change mine
