[El Aleman - Jens]

Hi guys,

right now travelling in South America/Peru on a KTM 990 Adv. brandnew, Bike runs terrible over 3000 m and motor just stops sometimes - it is really terrible!

Any idea what I can do???

Thanks for your help.... I see every day BMWs driving by.....

I don't own a 990 and in theory the EFI should take care of this, but have you tried the low octane fuel mapping? There should be a cable under the seat which when disconnected activates the low octane mapping. Should work better with low quality fuels at altitude I would guess.

Might be a long shot this one my old 950 Carbs version had terrible trouble with Carb icing and your symptoms sound similar. Although fuel injection is not as susceptible to icing it is known to happen and can be a problem for instance on some fuel injected systems - mainly on small aircraft engines. Just something to think about and hopefully eliminate it with use of an additive - if you can get it Silkolene pro fst really works well as a fuel additive to prevent icing - whether its available out there is another question. Another thing that is common but would happen all the time not just at altitude is the contacts in the bottom of the ignition switch can with constant vibration come loose, these are in the bottom of the ignition lock on the handlebars if you take the switch apart carefully the contacts have small springs that you can stretch out a little - and put it back together this should help the contacts make good and hopefully eliminate this problem. You can also bye pass the switch altogether in the fuse box by connecting ignition, lights and aux lights (three to the right of the fuse board) with 2mm wire then connect this to acc 1 (2nd from the left fuseboard) this will bypass the ignition key connection if it is at fault. ,Good luck with it. If neither of these help put another post up and I will try to scrape the recesses of my brain to look at another cause. Also when you say it cuts out do the electrics stay on or is it like a fueling problem ? Tchus. Jake..

Hi Jens,
kennst Du das LC8 forum forum.LC8.info :: Index ?

Da sind Spezialisten die sich mit dem EFI auskennen-evtl. hatte auch ein andrerer schon das Gleiche Problem->Forensuche.

P.S. bin grad in Mancora (auch Peru)

Speaking of which ... (and no offense to the HUBB), the ADVrider folks are usually pretty good (and quick) when it comes to tech stuff, so try asking your question there.

Hi guys,

yesterday we disconnected the low octan cable - no difference. Bike still runs bad... 1 KTM on a Pickup-Truck, the other one ride more or less...

Tomorrow our tour is over, but still over 600km to go - Puno to Arica

I let you know if we make it!

See you at the HU Germany or HU Italy Meeting - Jens
