On the bike in my sig, the OP changed and filter it as well as had the valves adjusted last October (I have the receipt from the shop who did the work).
Later this week I have it scheduled to put plates on my bike for three months. Should I change it's oil? Through the sight glass it seems pretty clean. I've been told that you should change bike oil once in the spring when getting it from storage, and once in the fall before storage, is there any truth to this? I really dont' wanna cause excess wear to the clutches in the transmission (bike has 15k miles) I plan on running Rotella T 15w40
thanks in advance
