So I was recently enlightened to the somewhat common issue of 2007 and earlier camshaft failure, and now I'm wondering if there's anything I can do to help diagnose the potential hazard or mitigate failure. For some reason I've only read issues on 2007's, even though I'm guessing all earlier models have the same one. I do hear a little bit of noise when the bike gets warmed up, but have assumed it to be normal top end noise (no real knocking or excessive clatter). Does anyone know if it's mostly just exacerbated by hard launches or tracking it, or if it is just one of those things you just cross your fingers and hope you're lucky? Just looking for some peace of mind if I take it on longer rides, and to keep me from selling it pre-emptively for an 08.
