May just need a hone with new rings, or a bore over? No need to throw out the baby with the bathwater
Isn't it a "Nicasil" coating. Not sure I have that right.Sure but at a litre-ish every 7000 km (which is more than what I'd recommend as an oil change interval!) it's not a concern. It would use half a litre during what I'd consider to be a normal oil change interval. You wouldn't even really have to add anything between oil changes, just keep an eye on it in case anything suddenly changes.
Even if and when it does start increasing - Adding oil is cheaper than a rebuild ...
The newer engines that use plated aluminum cylinders (I'm not sure if the SV650 is one of them) supposedly can't be honed using standard honing tools and obtain a good surface finish. In fact, one of my bikes is an oil-burner because of this. The factory service manual recommends "nothing" i.e. replace the crankcases, the cylinders are built into the upper crankcase on this and a lot of newer engines. It doesn't say anything special about re-ringing. Other people said hone it like normal. Other people said you had to send the engine block out for a special procedure to be done. Others had work-arounds.
Given conflicting information, I followed the shop manual "nothing" although I knew the cylinder walls were a mirror finish. (If I didn't hone the cylinders and should have, I could always go in later and do it. If I did hone the cylinders and shouldn't have, the engine was ruined. So, "nothing" was the way to go.) Result ... High oil consumption, about a litre every 1000 km. It needs to be honed ... somehow.

My linkage bearings were seized. I did rear wheel bearings too. They were sounding "gritty". Crush drive rubbers get pretty hard by that point as well.120k on one of mine, engine and tranny are just fine. Just need wear items(tires, brake pads, chain and sprockets) refreshed.
Does that mean you have to change your name?My 2000 VFR was at 110,000 km when I traded in last Spring. Dealer did compression test and it was at top shape and I never added any oil other than oil change. It was still at top running condition. Only reason for trading it in was for the lubless shaft drive and the factory panniers for the long rides that I normally do these days.

The bike is a 2006 SV650, using Rotella T for the past few seasons. I've never noticed any consumption before and I've had her since new.
Say what you will about the SV, she's my baby for the next few years at least. I'm just overly forward thinking.
Thanks all!
imo the oil should be getting changed more often than 7000kms. 5000 kms is my regular oil change time. 7000kms / L is normal usage.
