2013 TE310R throttle sensor/body

I can gladly report that a KTM TPS part# 77741077044 works as a direct replacement for a 2013 TE310R, with no modifications required.

Regards
Sergio

Thanks for the feedback Sergio. Any issues or installation notes? (or pictures?) If you know the KTM bike model and cost, let future readers know.

As I mentioned it's a straight swap, picture below along with the KTM bike model details.
Also note that I have updated my first post to assist future readers so that they don't have to read all the correspondence!

(upside down and can't seem to correct??)

excellent! And it's good that your preserved the original conversation too.

Holy sh*t!!! I just realized you paid $402.80AUS for your TPS . ...well, take comfort in the knowledge that your investigation will help other people in the future.


and I was going to say it looks like your fuel line Quick Disconnect is not fully connected; but after looking at mine, I'm not so sure now- might wanna give it a push just in case.

A lot of money for such a small part.

It's cheaper than spending AUD 1,200++ for a complete throttle body as OEM TPS's for this model don't come on their own!

Thanks for all the info.
That was a lot of work.

Hey Sergio- did you ever happen to get the resistance range of the new or defective TPS? lmk

[note to future readers: KTM part# 77741077044 can be found for under $150 in the USA without too much trouble- 2017 prices. Still, that's ridiculously high for a glorified potentiometer.]

May 2018 edit: also, the resistance range of the stock TPS turned out to be 130 ohms to 5050 ohms (probably 5000ohms- meter error) unmounted on the TB. when mounted, the no-throttle/idle resistance was 730ohms, and full throttle 3920ohms. With an accurate current source (like DM reported) of 1mA this also would equal the the voltage reading in mVolts (or in volts: 0.730v and 3.920v). The throttle body I used was off a low-hour '14 TXC 250R.

If any of you people are still out there - thanks for all the good info.

I'm having an issue with my '13 TE310R and I'm running out of options. The bike will reluctantly start, run for 20 seconds, bog under acceleration, backfire and dies. It seems like it's not getting enough gas - uses what is in the lines and craps out. To that end, I swapped the fuel pump and the regulator. The tank (regulator) was pretty slimed up, so I thought maybe the injector was clogged - took it out and bench tested and cleaned it - looked good... no help. I swapped the injector to be on the safe side... no help. I pulled the valve cover off to make sure the intake camshaft didn't slip - looks good - Both cams were at the proper position at TDC - checked the valve clearance - spot on. Good spark too.

So now I'm at the dreaded TPS. For grins I unplugged the TPS and started the bike - runs the same as when connected. I was thinking I was onto something - found this thread.

I've removed the TPS to try some bench tests - At 20K on the ohms meter, at 'idle' it's sitting at about 150 ohm, wide open it's about 5200 ohms - I didn't see any point where it shorted or bounced in value rather than straight increase or decrease, but I did see that when I go back to idle it's stop at a random point between 160 and 200 and slowly drift back to 150 - also, if tapped (finger snap kinda thing) will have slight (20) changes in value. I hooked up a 5v power supply and I can see that the output varies on the throttle positions, so it 'seems' to be doing what it should.

I'm hoping to have a definite answer on whether or not the TPS is bad before dropping $300 for what should be a $20 part

If here's anyone still out there and has any ideas, let me know.
