2013 agility timing chain removal/adjusting

[2pac]

hello
i actually own a 125 Movie but i guess the agility has the same or very similar motor.
my valve timing is probably one tooth out. is it possible to remove and re-install the chain after releasing the tensioner without removing the camshaft? if not- what tool is required to open one link in the chain?
thanks

You can remove the chain from the cam gear with the tensioner removed & the cam still bolted in place, if I remember correctly.
