Whoa... Um... well, I'm not knowledgable enough to really help you, but maybe you could expand a bit upon your statement???

"revved it up to 8000RPM" Do you mean under load or in a neutral position?

How many miles are on the bike? If I recall, the R1 doesn't redline until at least 13,000RPMs, so unless you're in the break-in period, a mere 8000 shouldn't harm a thing. Heck, I've revved my GS500 over 8000 and not had any problems!

Have you done any modifications to the bike? Did you buy it from a private party or a dealer? Many more factors play into this than you may realize....
