A rattling sound coming from my engine?

Im hearding a rattling sound comming from my engine. Im not to sure what the problems is. To be honest I wasnt really nice to this engine.I just mixed fuel by sense.

What can I do about this? Im not a pro at taking apart these engines though. I still heard the noise when I was riding at high rpms... Its not REALLY loud, but its noticable. Someone told me that its probally the piston ring that is worn down?. From this engine on im treating SO much better!! I learned my lesson! I only had about 250 miles on it sofar. But it still pulls really hard though. No loss in performance, just that rattling sound!!

That rattling sound is most likely your wristpin, just ride it.

Wristpin? What is that?

That is the connector between the piston and the rod. The bronze bushing gets some freeplay in it and it rattles. Sounds ominous, but I had one bike for over 1000 miles that rattled since new.

it might not even be the engine, on my bike everything rattled, the gas tank lid, the handlebar joints, all of it,

if it is the engine than ya its probly your wrist pin, my bike ratled for 2000kms, it didnt bother me, it got so loud at the end i needed ear plugs, but no big deal, if it runs it runs, but dont mix the fuel by chance, i always make sure im 100% on my mix,
