Just had mine fixed with the new seals. Maybe not such a big deal if they don't work. But another was having his fixed a second time at the sister dealer I was having mine fixed at. The dfirst time they just replaced his head with the old oem parts. Ticked a gain. This time they used the new part numbers and seals.
I was just thinking, oh my head hurts now, but is Yamaha gonna continue to fix then out of warranty if they have already been fixed at least once?
