You can send your second ring in for a cost to be made into gapless. Or buy a set from Total Seal. Note other vendors here market generic rings sent in to be made gapless by Total Seal as noted above.

I put a grand total of 4 miles on it fogging mosquito's since I "rescued" it. They couldn't get it to start anymore.

Total Seal Gapless rings?
Any comments about using a gapless ring set in a turbo 6.5? (Yes my 6.2 turbo hybrid needs a ring set.) Curious about power, MPG, blowby vs. standard gap rings. Will be used for towing... Do they have a 1st/top ring gapless set vs. the 2nd middle gapless ring? I would be concerned about...

The ring manufacture has their own specs normally .... True Total Seal complete sets are different than others, and each ring has a different gap as well...

Harley cylinder jugs requires honing plates top and bottom before boring the jugs, honing to size and fitting the pistons.
I once had a 1976 FLH Electra Glide. I wanted it punched to 0.020 over. The local motorcycle dealer had the boring bar but they did not have the honing plates for the cylinders.
At work, removing old cutting edges on loader buckets and installing new edge, there was always about a foot or two of new cutting edge that got torched off of the end. That stuff is relatively hard.
I took two pieces of the cut off ends and drilled and threaded a set of boring plates. I dont know how many drill bits I used and how many taps it took to get the job completed but I got it done.
After I was finished, I took the plates to the machine shop and had them planed to bright, shiny and totally flat.
One of the mechanics at the motorcycle dealer worked on a lot of Harleys in his spare time. After He bored my cylinders I handed the plates back to Him and told Him He would need them more often that I would.
