As KTM originally assembles pumps made in China, and in the case of replacement requires an astronomical amount of money, I decided that while we live in Europe, we will test another pump manufactured in Asia. I put it on Monica’s motorcycle while modifying filters, fuel hose, etc. KEMSO pump, officially from Japan, but produced we know where. Apparently a lifetime warranty, apparently does not cause so many problems. Time will show. And it costs as much as nothing in comparison to the genuine.
The pump test outside the tank showed her vigour, although I can not measure the output pressure. The difference that has to be kept in a mind is a fuel hose mounting neck. It is not corrugated but smooth, making it easier for the hose to slip off. The coarse-grained sandpaper has done the job, the rough surface gives good grip while the hose is tightened with a stainless steel clamp.
So far both bikes behave normally and I did not encounter any problem while rode them, but it is to early to swoon. If I have any problems while using any of the pumps, I will write another update. If, however, everything works properly, we will have two original pumps for a rainy day. 🙂

Anything to report back on how the Kemso pump is going? I’m about to replace mine also.

So far can’t complain, the pump is doing its job. On a 23 of August, we head to Albania and the pumps will be used much more than we did so far. I think it may uncover any defects if there are any ?

How is the pump holding up, did it survive Albania?
Luki · 16 October 2019 at 00:10
Yeap, it “survived” and still running strong. The pump has done so far almost 9000 km – the latest trip through Albania was 5500 km. At this moment no noticeable issues with any of the pumps.
IMO, most of the pump problems in 690 Enduro is caused by dirt. A good quality filter before fuel gets to a pump is essential.

The pump is still running strong? What’s the mileage?
Luki · 13 January 2023 at 17:59
Yes, both pumps are still alive. No issues so far. Mileage will be approx 15000 km.
