I will hang all of them up tonight in the basement by their thumbs!! I will use my wife's favorite cotton blouse to wash off my thumper this evening also, I'll tell her it works so nice.
I finally found the culprits (HOORAY)!

yet one will fowl plugs and one won't.
The dealer told me that it would be a free fix due to Yamaha admitting that some of the factory set TPS's were incorrect.

me that Yamaha Australia had informed them after many complaints that "YES" there was a
TPS problem, from factory setting. Now I
stand to be corrected, The dealer I spoke to said that they would do for FREE any bike that they had sold, otherwise it was about an hours worth of work to fix it, it was on the lines of setting the TPS to the lowest setting then holding the bike @1800 revs and adjusting the pump aswell, he didn't go much further than that, and assured me that was the fix. As I havn't fowled one plug I wasn't all that interested. I'd read many posts on this site about fowled plugs but it was an issue to me that had never occured and I was under the impression you guys had it sorted out with jetting etc.
I could possibly find out more or give you the dealers details in an E-mail.

Anyway, the moral of the story is that we spend muchos dinero on our fun machines, keep an eye on them.

Thanks for the tip. The TPS is easy enough that most "electrically" inclined could do it or at least check it. The pump adjustment is interesting, I wonder how many turns in from the "touch point" that would be.

IF not....repeat, only hold throttle WIDE OPEN. Comp. Release in, throttle WIDE open, and KICK LIKE HECK until she fires. She will.....just be ready to release that comp. lever, and back off the gas FAST.
