Once your bike and the oil warms up crevasses can become more leak prone and oil becomes less dense making it easier for it to find its way through open spots. I would get the bike warm and then with the bike still running do a close up inspection to search for the trouble spot. Hopefully its just a top end gasket which has usually been the case with me.

SOURCE: oil leak from tube
Sounds like your hose for draining the engine oil to me, there is a plug in the hose with a screw-ring that should be tight round the hose before it slips into a spring clamp on the bottom of the frame just behind the gearbox on your bike, hence just in front of the rear wheel. I suggest you have a look there to start with anyway

You have a crankcase breather hose that may be blocked, allowing excessive oil pressure to push oil out. It should be routed to the airbox. This may also be the overflow hose you are speaking about. Your oil type may not be suited to a motorcycle engine, automotive oils are NOT suitable for bike engines for many reasons, notably shared gearbox and engine oil and a wet clutch. Check function of the oil pressure switch as this should send a signal of loss or excessive oil pressure. Check your manual for correct weight and quantity and type of oil filter needed. The oil level is indicated on the stem of the oil filler cap.

Based off my experience today...which lasted several hours of researching this same issue on my 1993 Honda Shadow vt1100, it's most likely not oil but is rather fluid leaking out of the master cylinder that operates the clutch mechanism. I'm assuming you have a hydraulic clutch like mine. Directly above the kick stand is a metal plate that looks like it could be part of the engine but has an 8mm bolt holding it on at the bottom. Take that off and directly in front of you is your cylinder. You should inspect the lines and bleed the clutch lines to make sure that air isn't you issue. Beyond that you are where I am now.....did all that stuff but can't figure out my issue. Just thought I could catch you up at least that far and save you a little time.
