    Thanks for advice on pistons. Yep I did see the color system for the bearings.

    What about the recommendation in manual of using new bolts for crankcase and other areas? That yamaha wanting to sell more parts? How much difference that going to make in an average build?

    Pistons will come with new wrist pins, I use WSM. Rods are probably fine. If the bolts are TTY/stretch then there will be a measurement in the manual. I believe there was when I did mine and they were all OK to reuse.
