That is almost exactly what I got on mine (DS 1000) when I checked them after I did the frequency deal myself. I used cycleworks belts and set them to 110 Hz. However, I am going to back them off to around 100 HZ after they break in for a while.

The 5mm. allen key trick will not work for the 1000/1100 engine.  I don't know about the 697/796 engine.

My Pantah has had the same belts now for 5 years.  Going on about 25k miles.

It's garaged, rarely run in the rain.

I inspect the engine now and then and it's due for some head work.

I figure I'll swap the belts then.

"Yelling out of cars, turning your speakers out the window to blast your music onto the street, setting off M-80 firecrackers, firing automatic weapons into the airâ€"these are all well and good. But none of them create a merry atmosphere of insouciance and bonhomie quite like a revving motorcycle.

Port polish and ceramic coat exhaust port at same time, hmmm?

probably overkill for this bike but i am definitely having the valves looked at.  possibly new guides and 3 deg valve lapping and mild intake polish.

Although that is what my vertical cylinder happened to be at with the stock belts and factory tension before I replaced them. Horizontal was 3 or 4 mm. I forget which. I guess that goes to show how much they loosen up over time. Anyhow, I think the bike runs a little better now with proper tension but it ran fine before too (if you don't count the annoying leanness that this engine comes with).
