Whoa. Sticker for your '08 was $6300 with $300 freight (and then you paid $6600 - $400 = $6200? The local Yamaha dealer wants $6500 + $100 registration fee (everyone must pay) out the door; it started at $6900 (+$100 registration fee), I called them right after I read your post. Doesn't sound like much of a deal to me. Hmfff.

It's such a pain to negotiate these things I'll be shopping around more.
I sat on FZ6s yesterday and seats didn't seem bad -- but I know things get different after a few hours on a sunny ride. I'm guessing it'll be ok as it is with you.
I'm not so worried by the buzzing since my old CBR 600 F4 buzzed and I just thought that was part of its personality. Plus, you'all seem to have solutions to try already.
Thanks,
Dennis
