I had my chain tightened at 1,200 Miles. Ran great since there was a annoying buzz sound. Yesterday, I accelerated pretty quickly and around second gear to avoid or to be honest to waive off a dog . 1/2 mile later I accelerated and noticed a "griding" noice coming from the chain and seems like the bike is struggling to acclerate. Engine sounds normal at idle, but just not performs normal. Turned back and parked. I hope this is not a serious problem.
I wish I had a rear raise stand.

Sounds like you had someone else tighten your chain. Check to see if they tightened the axle nuts properly, or if not, if your axle has 'shifted' changing the chain run (one side will be further forward than the other side mis-aligning your chain).
I noticed a noise coming from the bottom of my bike, and it turned out to be the chain hitting the exhaust (it was too loose). I adjusted it, and gave it a try and it started doing the grinding noise you may be talking about, it was because the chain was too tight. I readjusted it and now I have no chain related noises.
