no power for a sec while accelerating and then a big bang

lately ive been getting some big backfires while trying to accelerate. im on throttle and im not getting any power for a second before it pops, i have learnt to cancel out these pops, but its getting annoying and i want to figure out what the cause is.

i know it could be temperature change that is making some kind of pressure in the tank and some water (or something like that) is being generated in the tank when the bike is standing still.

i also have an issue with the bike where it ticks, that might also be one of the issues because i believe the ticking is comming from the timing chain tensioner being bad. and with that tensioner being pretty much the "heart" of the timing system i am scared that might be whats causing the popping (if anyone has any tips on the best way to change that one out, let me know)

Has anyone ever experienced anything like this? if so how did you fix it.

PS. its only doing that big pop when its been standing still for a while

Another thing that might be worth mentioning is that i have a akrapovic full exhaust system with i believe no cat on my bike
