Crashalot,
I would just take a look down the water jackets, I swear it was so obvious as to why it broke where it did, from that casting. I do not feel that mine would have held up with stock compression at 99mm.
Our elevation really does change teh static, so I would tend to think your OK.
Performance,
I have no expectations for beting anyone, I just want to have a
bike that scares me once in a while (without having to click 5th and pinning it down the mountain). It should run, and good, hopefully it will stay together, thats what I am hoping for. I am going to be looking really hard at a Z450 (if it shows up soon) and making one of the two a serious hill shooter and keeping the other as a duner on pump gas ( I still have a complete stock top end).
