Over Revving

[apache]

I stupidly allowed my 74 yr old Aunt to Rev my bike from a cold start.
And more stupidly I watched her do it!

What damage do you think this has caused.
It may be just in my head but i think exhaust sounds a bit louder, the engine a bit noisier.
It drives and accelerates fine.
Mileage is 85000 (in miles)
Should i get the bike checked out?

Thanks in advance.

Revving a cold engine to rev limit and holding it there is one of the worse things you can do to an engine.
The cold oil wouldn't be lubricating the engine fully and you are really stressing the bearings, rods etc due to the cold oil and no load.
Hopefully you haven't damaged it too much. The louder sounding engine is a worry though.
Just keep riding it and If the engine sound gets worse then I'd get someone to take a look at it.
