i was going to suggest battery voltage too...

This happened in my RX8.. chased the problem for a while.. until i replaced the battery. Ran smooth after that.

These batteries do kinda suck.

The only time we had a RE do something like this, it was a clogged injector. Started out like yours then got worse in time. You may add some known quality injector cleaner to see if symptoms change. Doubtful it will fix it, but if it changes, well there you go. We replaced the injector under US warranty.
Duc Sco is correct, on the battery. Check static volts, and what it drops to with key on, then when cranking. After startup, it should recover within a minute or so.

Hi Variateur,

Also check the connector from the ignition switch under the caskeet.

Mine was half way off and kind of flopping round a bit... surprised bike didn't die while on the freeway. The locking tab on the connector wasn't locking properly, so a little bit of bendy bendy sorted it out.
