Are you sure it's the chain and not some gearbox issue, etc, doesn't sound right at all to me.

When I get a spare few minutes I will put it up on the stand and go through the gears to see it it still does it.
I'm sure it's jumping about a bit in all gears when riding but may just be in my head.
Also not sure if rolling on throttle cures it or not as it doesn't feel jumpy under acceleration, or not as jumpy.

it's caused by backlash in the gearbox components. both my SV's have always done it even a brand spanking new one just out the crate.

you have a problem if you can feel a pulse while riding and usually indicates a tight spot in the chain.

might be your riding as v-twins don't like low revs. try keeping the revs up a bit even if you have to drop a gear.

v-twins usually make considerable torque at low rpms. I find them working comfortably at much lower revs than in-line 4's, and my '00 SV650 is happy at 3,000, doesn't really complain even at 2,500.

How many miles have you put on the chain? And what brand is it. About 2 years ago I put an RK chain on my SV. It was very tightly made, stayed kinky for 1,000 miles, then relaxed, gradually stretching to it's actual design operating length. I was unhappy and won't buy another RK for quite a while. It did the same thing yours is doing when run on the paddock stand, otherwise, OK, though I got about 5,000 miles fewer than usual out of it.

I change up between 5k-7k rpm most journeys. If I go out for a spin I'll rev it higher.
30-40 limits I'm usually in 2nd or 3rd
40-50 limits 3rd or 4th
50-80 4th or 5th

If that's changing up too early I best get better ear plugs

I've never had a problem with DID chains.
Is it kinky anywhere when just sitting? Is it tighter in one location, and looser in another, as in, check the tension at various places?

Riding on the roads, I usually plonk along lazily in high gear or fifth. Our usual pace is around 65 mph, slower when necessary. Even tight hairpins up and down the mountains, I mostly use 4th and 3rd, rarely rev above 7,000, usually not above 6,000. I try to be smooth and keep my corner speed up. The SV makes it easy.
I bet I get better fuel economy than you do, and use less oil too. Not that that's what my fun is about...
