Surging when Engine is over 85deg

Post by Katomic » Sun Mar 08, 2015 5:47 pm

Hi all,

I have a 2014 1190 Adventure with EDS. Great bike except for a few KTM'isms.
I ride it around 800-1000km a week, so this one is real pain.

A typical ride to work starts at the Gold Coast, and after 5-10 mins on the highway sometimes longer, the bike begins to surge badly. So much so, I've had people look at me from cars, thinking I'm reenacting some sort of sexual conquest from the Mardi Gra.... But no, it's just the bike surging so badly it makes me embarrassed to ride it.

Now, from my 'testing', it has become aparent, that the bike needs to have an oil temp of usually 88-91 for it to begin to surge. This morning for example, I rode to work at 2am, and the engine oil temp did not go over 82deg, and rode smootly all the way to work.

Typically, a ride home in the afternoon, it surges terribly all the way home. Outside temps 28-38deg, with engine oil temps 90 and up.

Knowing I cannot use Tune ECU to turn off the O2 Sensors, and the bike is totally stock EXCEPT for, Uni filter and snorkle prefilters, is there anything that can be done?

I'm at the point now, I hate riding it so much due to this (and a few other minor niggles), I'm wanting to sell it and go and buy another BMW. (my previous bike was a R1200GSA LC)

When will KTM Get their act together with their fuelling? This is my 3rd KTM and they are still having the same issues!!!

You need to make some O2 sensor eliminators, that will sort your surging. viewtopic.php?f=29&t=6897

How is the bikes full power does it feel down on power as you could have a fuel filter starting to block up.

Thanks lads. I figured as much.
I checked Rotweiler Performance, and their O2 Eliminators are $40 + Shipping, which works out to be $100! (AU)

Cheers. I'll make some plugs and see how it goes.

Kevxtx,

SORRY, forgot to answer the other half of your question. Full power is fine, hot or cold. Response is fine too. It's just constant throttle surging, most noticable and horrid, when ambient temp and engine temp is hot.

Don't suppose in all your fiddling with the Orange bikes, you've tried a 'Boosterplug' , or, at least know of any major benefits that O2 eliminators don't do?

I'd be interested in getting a Booster plug if they work well. I've ordered the plugs etc to make some O2 eliminators as per your post, but wondering if the Booster plug is a better alternative? A bit like your O2 modulator doohicky?

Well, I've given the O2 sensor eliminators a good test, also, installed a BoosterPlug with and without O2 eliminators. The BoosterPlug does a great job to help with throttle feel, but actually, I found the O2 sensors alone, made the bike stronger in low revs and less 'chuggy' in 6th gear on the highway.

Unfortunately, neither the BoosterPlug or O2 eliminators helped my bike with the surging issues over 85deg C engine temp. Nothing seems to fix it. Checked fuel filter and breather hoses. Filter had a little bit of stuff, but not much, and vents are fine. I'm over it. Selling the 1190.

Thanks to those who tried to help. ;)

I would be looking at a custom fuel map, or at least get the area's A/F ratio checked.
