No experience but certainly some thoughts - I am in the same position as you and will not pay the original Yamaha parts price. I don't doubt that these Chinese parts will work fine as they really are just a lump of metal that spins around with some magnets - As long as they are dimensionally correct and balanced then there is little to go wrong. I would not try unbranded con rods or valves but the rotor does not worry me. The parts look pretty good in the picture and I will get to changing it in due course but it has lasted for 32,000 miles and 15 years so I don't expect it to grenade in the very near future.
