I got my 2004 savage in 2012 with 400 miles on it, it sat outside and had some water damage. I got it for just about free and it ran just fine for about 1000 miles, then I decided to take a long trip. Kentucky to Minnesota, mostly interstate... It was a nightmare, needless to say I made it but the savage was hemorrhaging oil the entire way while sustaining freeway speeds. The jug had an indentation on the inside and my mechanic said as opposed to replacing it I could send it to this performance atv shop his buddy ran and get it resleeved with nickel. I went that route.
I was basically ignorant at that point and the explanation that I got was that it was "better" which made me happy because it was cheaper than the new jug.
What does my fancy sleeve do? Anything?
It does run absolutely perfectly after that.

Was a sleeve put in it or was it plated with Nikasil?  Nikasil is short for Nickel Silicon Carbide which is used by several motorcycle manufacturers and is generally a good durable lining.

Since it now runs well I would say that it fixed your problem by providing a hard smooth cylinder bore of the correct dimension.

it's common to "re-sleeve" many piston powered engines.. many highway diesels get re-sleeved at major overhaul..

you did good

I'm just curious... When they resleeve the engine, do they bore it out the thickness of the sleeve so the piston size remains the same? In other words, if the sleeve is 1/2 mm thick, do they bore the engine 1 mm so that the same size piston can be used?

Yea, the piston size stays the same. They bore the block, OR, some blocks come sleeved from the Fak Toe Ree,, Then all they hafta do is get the old sleeve out & slap a fresh one in. IIRC, Detroits are that way,
The block has to be very close size to the sleeve, or there will be hot spots. The sleeve cant just slide in, it needs to be Tight,, for physical support and heat transfer.
