CG125 slight rattle, is that normal?

I've just got my CBT and bought the first bike I've seen and ridden. I
know that's not really good practice, but CG125 and YBR125 just are not
coming up that often in my price range.

It's only after riding it for a good while I've noticed it sometimes
rattles a little when I'm having to accelerate or give it reasonable
throttle. I've also noticed that the gear box can whine a little when
slowing down and you're still in a gear that's too high for the speed.
Would you say these are reasonable normal for such and old design of
bike as the CG125?

2004 CG125 with approx 2500 on the clock. Seems to have been looked
after and performs as well as I'd expected. Given the reviews saying
it's pretty much bullet proof, I'm not really expecting any issues with
2500 miles.

Thanks for any advice.

Yes. It's a pushrod engine[1] so can be expected to be a bit noisier
than the usual OHC.

Gear whie on the overrun is normal.
