I went back to my dealer. He checked but no bulletin have been issued for my early 2013 S10. Not even something about the CCT. According to the guy in charge at the dealership, it does not mean there won't be sometime in the future. The answer we got from Yamaha seems to be that if the customer complains about the CCT and the bike sounds weird, Yamaha proceed to the replacement. But that is just speculation on my end. Maybe that's just because I have a warranty for another 4 years, I am riding 14K miles a year, and it's cheaper to take preventive action than rebuild the engine.
Cory, with your 600 miles are not exactly in position to complain about some noise in the CCT. It develops long after that.
Nevertheless, hat-off to Yamaha for taking action on something that only very few of us have encounter with disastrous consequence. Even without a fight!
I am sure many KTM and BMW customers would love something similar. Anyway, that just comfort the S10 reputation to be rock-solid reliable!
I am getting more of a Yamaha fan by the mile! ::022:: ::022::
