I'm having a tough time with this. Did they strike the pistons ? Evidence of galling in the guides ? Valves do not bend without contact with a piston. A very unusual failure given the care you give the bike. Any chance of close-up pix of these ? You never replied about losing a cylinder at time of noise, I'll assume you did. Both in same cylinder ? A loose guide that passes oil does not stick it's valve. There is a condition that occurs in some motors now that is fuel related. The intake valves stick because of a deposit of a fuel additive that gums up the guides. Invert the head and spray carb cleaner or oven cleaner down the guides and allow it to drip into a clean white cloth. The deposit is a dark brown color and very stubborn to remove. This has not happened to exhaust valves. Have the guides cracked as well ? I'm very curious about this. Failure is a PITA, cause is vital.
