New spark plugs
I bought new spark plugs over ebay this morning. NGK IRIDIUM IX SPARK PLUG CR9EHIX9 CR9EHIX-9 No. 6216
Anyone tried these and know whats the difference between the non-iridium CR9EH9 stock plugs?

I've only run the iridiums in my CBR, but in my XR600R they made a pretty big difference. It ran crisper at low throttle and with big changes in throttle, and never fouled. You get more spark from them because the iridium conductor has less resistance at high temp than even platinum, and is more durable too. The coolest thing about the iridium is their lifespan. You will probably throw away your F2 before the plugs go bad.
