Folks, i got new chain and sprockets as advised by the big guns on the forum. The chain had developed tight spots and was missing rolers. When i finished lubing it a short while ago, i put it in gear to check if all was ok. I noticed that it slightly displaces up and down near the front sprocket (with the sprocket cover on) but nothing like a big deviation. Bike was on centre stand at that time.  Sooo... should i again go to the mech tomorrow??? I bunked from hospital to get it done as don't get time due to shifts at work place. Don't want to go again all the way  ... diagnosis needed please. Thanks in advance 

Just rotating a new chain on the center stand is OK,but not always an indication of problems after installing a chain. A new chain will be a little tight (most likely at the master link).
You need to go ride and let the chain loosen up.

As always... one of the big guns to prompt rescue. Thanks a bunch sir @adidas guy 

agreed. let us know if any further issues Eh?

Sir @yamahaonkawazuki, will do. Thanks for the concern, so far it seems to be kinda OK. Cheers
