My 2013 has a 2014 cam chain tensioner from factory

I bought this bike new and just did the 2014 clutch basket and figured since I was in there I would put a graves manual cct in there while I had the cover off. I went to remove the cct and stamped on the top is 2BS, not 23p . My clutch basket is definitely gen 1 but I have a high vin #. I think I will leave it alone for a few more miles since I only have 11k on her with no issues with the oem cct. Anyone else seen this on there gen 1?

It would be interesting to know when Yamaha knew about the issue and superseded the part. All this "that's the first we've heard of that problem" that those with the start-up clatter gets to hear when they go in. I don't think the few major failures we've read about here were all limited to the '12 only, but in my mind the failures were a '12 thing. They may very well have 'fixed' things by mid to late '13.
