I have recently had a slight loss of oil on both sides, only behind.
Do I have to open the valve cover or can I do something else?
Thank you.

After doing the valve clearances on one of my other bikes I experienced a very slight weep passed the rubber gasket which settled and stopped by itself after a month. You could take that approach if this is a tiny leak, it won't harm the bike. If it persists then a reseat of the valve cover gasket and some black RTV Silicon Engine sealant around the semi-circular sections is normal (and recommended by Honda) and that should sort it.

Look at that beautiful, tall, silver lump.

Why did we only get red and black CB1100's in the States?! I think this bike looks awesome in white, blue or yellow too!
