I did the same thing at the racetrack a couple of months ago. I momentarily saw ~7500 on the tach as I let the clutch out. Got the clutch back in, rev's came back down, and made the correct shift.

Then I cussed at myself inside my helmet for the next three laps. Out loud.

Then I realized that there isn't much you can do about it. What's done is done. Obviously its not "good" for the engine and I am careful not to repeat, but as long as the engine keeps running fine then it seems that I dodged the bullet.

Only you can deicide if you want to drive it. I did and everything has been fine but your mileage may vary.
