Any one have any major mechanical concerns with the ZR 900 motor?? *I think i might order one for next year, but I read some posts about the vibration being sooo horrible and that it is soooo big that it won't be able to hold together. *I don't really believe it, but I was hoping that some of you with more mechanical experince, or actual 900 seat time, might be able to share your opinion with me. *
I guess this it the next best thing since the discontinuation of the Tcat. *I've considered buying a used or left over Tcat, but not quite sure. *Does anyone think that they would be over priced now that they have stopped production. *There was a left over for sale on ebay and they hyped it to be "soon to be collectors item" and was expecting to get more than MSRP. *What does the majority think?

Thanks in advance for all rational responses.
