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. 🙂
