Bike overheats quickly
« on: March 12, 2016, 08:36:46 am »
My 2014 690 will go a couple miles from cold & before the temp gets halfway up the engine goes into a "failsafe" mode where it has no power. It sounds like the timing is retarded also. I'm pretty sure the water pump & thermostat are ok because the coolant in the tank gets hot. It would still be cold if the thermostat was stuck or the water pump wasnt circulating coolant, right? So I'm just fishing for ideas. Lets hear em!

I pulled the thermostat & it is good. Opens about 150F. Also pulled the water pump cover & the impeller is good also. It does not spin on the shaft. Sooo.. the cooling system seems to be working yet the engine gets hot within just a couple miles of riding.. This is at about 50F temps.

Ok, pretty sure I found the problem.. It's a bit embarrassing but if someone out there can learn from this it's worth the post. The air filter was completely plugged. I always clean it (K&N filter) at every oil change but forgot to do it this last time. I think my girlfriend was distracting me.. Anyways, I have the evo 1 air box lid & that lets a lot more air & dust into the filter. Along with a pretty oily filter it starved the engine of air I suppose. I never did get a temp light. So live & learn from my mistake!

Hi,

Just happened to log in here today.  Kinda surprised that it would over heat.  I would have thought it would be running rich in that situation.  I guess the bike is smart enough to lean itself out to compensate?

Glad you figured it out.  I get jealous when I see you ride by and I had to drive.  Planning on riding tomorrow though!

Well I thought I found the problem but after a 4 mile ride today it did the same thing. The temp was only halfway up when it entered failsafe mode again. I'm starting to think it may be an oil pump. I just changed the oil & when I came back from my test ride there was no oil in the sight glass..

is it not throwing a blinking code?  have you tried doing the 15min. reset?

No blink code or warning lights. Its like on cue, as soon as the engine warms up it switches maps & has no power. Still idles fine though.. I have the throttle body out now to get a better look at things & found the vacuum tube for the canister valve was kinked. I'm not sure if that could cause my problem but the valve does tie into the fuel injection harness. Hmmm. I replaced the line & will give it a try tomorrow. Having your bike down & out is the worst guys..

try this thread. it may have an answer for you.  seems like a few ktm owners have had the same problem.

and there is a recall on your bike's fuel venting system that sounds like it would create the problem you're describing
