longevity

providing that your sv has been maintained to a reasonable standard, at what mileage do you decide enough is enough.
mines creeping towards 25,000 now and still looks good and responsive.

If this engine lasts till 60k I will put it on eBay and fit a newer one.

I'd say 60k is enough to break. Which includes 5-6 C+S sets, 12 rears, 8 fronts, 15 oil + filter changes, 14 spark plugs, and lots of fuel.

We sold our first one with 50,000 on the clock two years ago, and it's still going strong

explain chris, not sure if your being sarchastic?
would you expect this one to last 60,000, but they normaly go bang before then?

More than a couple of SVs have made it to 100,000 miles. Others have blown up at less than 20,000. The ones that have lasted have been well cared for, the ones that have not lasted have generally been wheelied lots, and had their oil checked infrequently.

Of course if it hits a car all bets are off.

The simple fact is most SVs aren't kept long enough to do 100,000 miles, even the oldest ones are now 10 years old and most people don't keep a bike that long and average 10,000 miles a year.

I remember someone posting something about an SV making 120k and then blowing up but the guy only oil + filter changed every 5k so it lost out on 5 services. And generally the loom falls apart first.

Suzys first engine broke a bit at 22000, and rather than let it completely go bang, I replaced it with Pete n Lissa 27000 one, it hasn't run in a few months, but thats electrical, and I expect now that I look after things better and have learnt a lesson, that this one will hopefully live a very long time.
My other Sv has 33000 on it, and its tickety boo. Runs fine, has done since 28000 when i bought it, and i suspect that should live for long time too

Depends. Depends on everything. I would like to think I use the engine properly when on a decent ride out, dunno whether anyone who was on the ecosse run wants to comment on that, but I don't think I am too much of a poofter with it.

Mine's downgeared, and not standard. So cruising rpm is like 7000, not the best thing for it. Really blows stuffing out of exhausts quickly too...

But I run it on an ester synthetic oil, and it gets serviced well. So I reckon the 2 will balance out, and give me 60k, unless it goes pop for some other reason before that.

So yeah, 60k and I find a lower mileage bottom end and build that up for it. Maybe keep the old one as a spare or flog it. Dunno.

Some of the 99 ones also spun their big end bearings even when properly fed with oil

Something to do with the pumping effect through a port down through cases into the sump pickup area. No idea what kind of riding causes this though.
