at Pocono this past weekend I started getting a big hesitation/engine bog at 5-8k RPM when WOT. Was running fine the session before with nothing being changed (no new gas, etc).

2005 R6 with 10,000 miles. Slip-on is the only related mod.

I was really low on gas but not "out" of gas...

I'm wondering if it's plugs, they're the original.

I gassed up and took it out on the street tonight and could not recreate the problem at all.

A little worried since it was bad enough I pitted out after a few laps and called it quits for the day. Have another track day planned in 2 weeks. Hate to have it ruin my day..

Any ideas?

change the plugs and check the map. Those are the two primary culprits.

EDIT* You were do for plugs 2k miles ago, so it may well be the cause.

I just had a similar problem and it was the plugs.

I went to change the plugs today and what a nightmare! Someone at Yamaha has a sick sense of humor with the heat shield. and then after finally getting it out, I don't think I could have gotten the plugs out without a pivot extension on my socket.

Ahhh!!!!
