Well, there was a ticking/tapping noise, coming from what seemed front left portion of engine. From readin the forum, i thought might be CCT. Cut off engine, left it 2 mins , started again, and noise was gone. Repeated this a couple of times, and the noise came and went randomly

Also there seemed to be a quieter, knocking/tapping noise coming from a more central area of engine, is this anything to worry about?

Sorry for what might seem pointless worry, just wanna make sure i havent bought a binner

p.s is it safe or not advisable to have the bike in gear and running it on the stand? tried it very briefly and the chain seemed to be rattlin a lot.
