With no mechanical skills... there is a decision to be made here...
Do you want to get some?...
This requires buying some basic tools, getting greasy, sweating, and some serious cussing...
...if that sounds fun... you're halfway home...
If it don't,...
Concentrate on riding skills...
You say the bike is performing and running pretty well...
You can, with experience, and some analytical thought, learn to reduce and control much of the pops and backfires by learning to work the throttle and clutch...
Ride a while, and play around with these, and you may get a feeling for it...
Don't chop the throttle off,... use more front brake to slow, with less downshift...etc...
...and,.. first mechanical tip... check the two bolts that attach the exhaust pipe to the head... they tend to loosen, and if they allow air to leak... backfires will abound...
Don't be a brute, and strip them (using a ratchet,...they should take a little more than just finger strength to tighten... wrist, but no elbow).... but, make sure they are tight...
Welcome to Savage world...
