      Right so bike was running well, now, bike seems to only want to run on front cylinder, checked both plugs, cylinder one looks oily wet and smells like petrol. Compression test on rear cylinder  reads around 105psi cold throttle open, front cylinder  is around 135psi. Anyone ever had this problem? Piston rings or valve seals?

      Update, I do not think it is oil, looks like carbon fouling, and soaking in petrol.
