How to easily adjust the throttle position sensor on your KTM using a harness that greatly simplifies this task.
Sweet you just saved me from. ...buying the one for 100$ ...SWEET..can blow it another way...it is a good thing you've done...keep them coming
Nice, glad you went back to show us how to do the adjustment otherwise it would have been a waste. Where can I get that wire set?
jeffrey sisti Thanks for your comment! www.tpstool.com
Looks awesome!
I wouldn't say it totally negates the need for a power supply, but could in a lot of cases.
If your bike doesn't have an ignition or if your bike won't start because the TPS is so out of adjustment you would still need the power supply.
Having said that, this is way easy easier!
Thanks! I think this would definitely work even if your bike wouldn't start, there is no need to have the motor running to get voltage. However if you were minus an ignition or just wanted to work on the bench, then that would definitely be a case for a power supply. I was scratching my head as to why this hasn't been available earlier, and I think it's because there are services charging people lots of money to do this for them and they didn't want to cut into their own bottom lines. :)
@nadascurb did you found how much voltage should 350 have?
@@TimotejRoncak I've got 350 TPS video on my channel. I can't remember the voltage, but if you watch that video it is in there. I'd paste the link but it would probably be blocked.
I have a 2011 ZX14 100% stock with 8300 miles. I change the plugs and air filter at 7800 miles. At 3k rpm any gear, the bike will cut out at full throttle but run like the win around 5 or 6 grand. You just gave me something to try before paying M--- Motor Sports $140 to look at it. Glad u upload your video. BTW I have a few videos on cars.
***** I'm glad it was helpful! Put the meter on it and watch the meter while very slowly going from idle to full throttle. The voltage should change very smoothly. If you see any sudden jumps or dips in the voltage then that can mean that your TPS is actually bad. I hope this helps and good luck!
Matt South I keep getting different values for idle from different people. But I will try it this weekend. Thanks for getting back to me.
It will vary by bike model. I'm not sure for your bike, but the value should be in the service manual if you can get your hands on the manual somehow.
Matt South I checked tps and it is smooth from idle to max. It was set at .61 volts I tried going up to .68 volts and it got worst. I tried going down to .48 volts and that didn't help.Bike still cut out at around 3500 at full throttle.
***** It sounds like the TPS isn't the problem with your particular bike. I think it's time to start checking out other things. So at 3k rpm if you open the throttle it cuts out, but if you open the throttle at round 6k rpm then it runs fine?
@rustyATV - You can use the tool to adjust the TPS on your carbureted RFS motor, but it may not see as big an improvement as the fuel injected bikes. However on the carbureted adventure bikes, especially the twins, I'm getting feed back that adjusting the TPS makes a very big improvement.
thank you really very easy after having a tips with you .
ally77adventure Thanks for the feedback, I'm glad I could help. Enjoy your ride! :)
u are the man. thanks brother fr the tips.
Thanx bro that helps a lot 👍👍👍👍
Nice video.
I know my 500 exc is running lean because the techs told me when I got in dyno'd, so I guess I'll knock it back a whisker and see if it makes any difference.
+surg23 You'll want to raise the voltage a bit. Going for between .60v and .64v should give you a significant improvement. Start at .60v and test, then raise it to .62v and test. Keep bumping it up as long as you see improvement. There's a big thread over at Thumper Talk (dot com), the TPS adjustment thread in the KTM forum, with piles of details and feedback from other riders. I will try to post a link here, lets see if youtube lets me post it:
www.thumpertalk.com/topic/1077085-the-tps-adjustment-thread/
Matt South Thanks for the info Matt. I don't actually know how lean or rich mixtures affects the bikes performance, all I know is it has a weak idle. All the power seems to be there as it was right on 60hp at the time of testing.
Perhaps I should be looking for a smoother power delivery or something, only one way to find out.
Tweaking the TPS slightly won't have a noticeable affect on peak power at all. What you will notice is better starting, idle and smoothness at small throttle openings. It also helps to resolve flame outs. If it burbles or stumbles at smaller throttle openings then tweaking the TPS can really clean that up. Check out that thread I linked, piles of feedback and great advice in there.
Matt South Ahh I see! This could very well fix that laboring and stalling issue. It's the weirdest thing, to have all this power, yet it has zero tolerance for being in a gear 1 higher than ideal, shit I can put my GS in a gear 4 gears higher relative to speed and it just pulls no probs.
Perhaps this is the reason why I am not seeing this torque the bike claims to have lol. Thanks again Matt.
Thanks for the video, very helpful. Is there a way to disable tps?
Why would you want to do that? Just unplug it, but things won't run right if it's an efi motor.
If this an issue with the carbureted RFS motors, as well?
Is a "higher" number … from .57 to .64 mean its a little more "richer" … Im going to add a slip on pipe which will lean out my FE350. Is this my adjustment (TPS) that will make it more rich?
Yes, adjusting the TPS to a higher voltage will make it richer (more fuel).
hi , perfect your video. I need help with my bike. I have an er6n, and I need to know if the adjustment is the same to it!? thanks
Thanks for posting! I'm honestly not familiar with that bike, but the effect of the adjustment should be the same on anything with open-loop fuel injection. Check your TPS plug to see which model plug matches (compare against the pictures at tpstool.com), and also check to make sure your TPS is adjustable. Some are solidly mounted and can't be adjusted, but if there are slots for the mounting screws then it can be adjusted. I hope this helps!
Hello, I built a similar cable and tried it on a Husaberg 350-2013. The bike does not have the ignition key, and then I tried to briefly press the start button but without starting the engine. The tester does not mark anything!
Should I start the engine and let it idle?
Yes starting the engine should definitely show a reading. If it won't start then make sure you got the wires right and didn't cross any over. Also make sure your meter is on dc voltage. Good luck! :)
Yep, from what I can make out, it looks the same. Why does the yellow cable need to be split? Thanks.
The harness can be used for more than just setting the TPS position. It can also be used for diagnostics that may require access to all 3 wires.
How do u do it with ktm sxf 250cc 2012 kick start only do u do it same way bike starts but dies after 7seconds plz help
Check out tpstool.com, the powered tool gives you as much time as you want.
Hey I just bout a tps tool for my 2018 ktm 500 excf and I have not received the tool yet but I was out fooling around in the garage looking at getting to the TPS and on the 18 model it is not as easy to get to in your video. Instead of the rubber boot there is a plastic cover that has part of the Frame right on top of it? Do you have any suggestions ? Thanks
Thanks for your comment. The 2018 is not as bad as it looks. Follow this link and scroll down to the post by MyersAvionics where he gives a step by step with pictures. Please let me know if this doesn't get you going: thumpertalk.com/forums/topic/1077085-the-tps-adjustment-thread/?page=48
Great job , Thank you
Glad I could help! :)
I have a map switch programmed and installed at the dealer, should the setting be the same? Also, how do you keep that bike so clean? It's like as if you never ride it.
I would not expect the map switch to have much effect on finding the best TPS setting, I think if you were to test for the best setting in each map switch position you would end up at just about the same place. The video was shot right after I got the bike, so at that point you are correct it didn't have many miles on it. ;) Thanks for your comment!
what model do I need for a 2014 EXCF? I believe its model 2 but im away from my bike otherwise id check the connector.
The 2014 EXC uses the model 1. The bike in this video is a 2014 500EXC
@@8180634 would love to be able to confirm, it is a 2014 350EXCF. The website does not list this bike specifically
@@martinfilteau3220 I believe it falls under EXC 2016 and earlier. Easy way to verify, go to partzilla.com and look up the TPS. If it's triangular then it's model 2, if it's oval then it's model 1. They didn't start using model 3 on the exc until 2017.
This works great on my 2015 Ktm 450. But when we tried on a 2015 Ktm 350, it was way too rich. What is the voltage recommendation on a 350?
Thanks for your comment! Every bike is a little different, so just setting it to one specific number won't give you the best result. This is especially true if there are are any aftermarket parts installed (exhaust, etc..). If you're too rich right now, then take the current reading and move it down by 0.02v, then give it a test. Keep repeating as long as you see improvement. On a bike that is too lean, just do the opposite; take the current reading and move it up by 0.02v, then test. And keep repeating as long as it's getting better. You should find the best setting for your bike very quickly this way. I hope this helps, please respond back with your result!
hi. i want to buy this tools. mine is KTM duke 200 ABS. which model is the tools according in the website, model 1,2 or 3?
Lanzo Lan thank you for your message! I'm not familiar with that particular bike, but if you can send me a picture of the TPS plug then I can tell you which one you need. Send email to mwolfe [at] qualitysmart [dot] com
Do you know if they had this TPS before efi because my 04 exc has that or a similar sensor and I can't tell if it's TPS or some kind of auto fuel shutoff solenoid to keep the bike from flooding when off or tps whatever it is I think it's bad or in need of adjustment because carb/Jets/lean and rich screw are clean and worked flawlessly at this elevation until all the sudden it started to bog and stall when you attempt to accelerate without choke on so I think the tps is in need of adjustment or broken fuel solenoid is stuck in the off or broken position not sure what it is or if it's broken is it difficult to pull these sensors out are they attached to anything???
Thanks for your comment. Yes the carbureted bikes from back then did often have a TPS, but that does not sound like the cause of the problem you're having. Check out the accelerator pump. On carburetors with accelerator pumps, when opening the throttle makes it cut out or stall, very often the problem is accelerator pump not working correctly. I hope this helps!
Hi. I change the TPS for new. I have this tool. How i must set tps voltage? Throtle butterfly must by full closed , idle red screw twist off. My bike KTM sxf 350 15' Thanks for any help.
Thanks for your question. Double check the shop manual for the value, but I believe the factory setting is around 0.58V with the idle all the way out (throttle plate fully closed). If your meter reads in mV then it might show 580 instead of 0.58. That should be close enough to get the bike running (don't forget to turn the idle back up again) and from there you can easily fine-tune it by going up or down 0.02V at a time to see where you like it the best. I hope this helps!
@@8180634 Many thanks for quick answer. Tommorow i try to set stock setting. Now i know i must set at full closed valve.
Hi, do you think this would work with the 690? Looks like the same connection.
Thanks for your comment. I'm not personally familiar with the 690, but I believe some years this worked great on and some years the TPS is not adjustable. Here is a link to a thread about tuning the 690 and there is some good TPS info if you read through it. I hope this helps, please let us know your result if you give it a try! advrider.com/index.php?threads/ktm-690-efi-2008-2013-idiots-guide.931664/
How did you like the performance after adjusting to .64 volts in this video?
It is a significant improvement. The most obvious difference is no more burbling and stumbling below about 1/4 throttle, it is just smooth now. After a little more testing I ended up with 0.63v as the best setting for this particular bike. 0.64v was just a tad rich and would occasionally flame out in the really tight stuff, 0.63v is perfect, runs great and no flaming out.
If my service manual is 0.5v ,can I adjust 0.63v like u?have problems on my bike?
The service manual will give you the manufacturer recommended value and that's a good starting point. You didn't mention which bike you have, but if the TPS on your bike is adjustable (if the mounting screws are in slots so the TPS can be rotated) then you can adjust it to be a different value to see if that improves the performance.
Ive got a xcf 250 2011, when cold with choke out, the bike sometimes needs a slight blip of throttle to start and even when hot with the choke in still feels abit lean to me, just checked the valves and there near enough in the middle of tolerances so its not that! im cleaning the injector atm, but could the Tps need adjusting slightly richer possibly? any helps appreciated
danny cockburn It could never hurt to check and adjust the TPS, this has helped more than 1 person to resolve starting issues. But did the problem just start suddenly or has the bike been this way since new?
Im not sure ive just bought it, i wouldn't say its hard to start but it takes about 10seconds of turning over to get it to fire. It just could be better, its not lean enough for any popping though, but to me it does feel slightly lean, I'm giving her a good going over/service atm see if i can improve it,
danny cockburn i just had a test of the TPS and it was reading 0.49v's Ive increased it to 0.62v, so fingers crossed that should aid starting. ill know more by the weekend when shes all back together
thanks for your help
On the motocross ktm 450sx bike how do you turn it on with no key to get a reading? Or does it automatically get a reading as soon as you hook everything up? thanks I need to do this.
Thanks for your comment! If you press the start button briefly, the TPS will get power for about 8 seconds. You can also start the engine and let it idle and there will be power the whole time the motor is running, but just tapping the start button for about half a second will power up the electronics for about 8 seconds.
Also go here and scroll down to the post by "MyersAvionics". He posted a nice HowTo with pictures for a 2017 XCF, which should be very similar to your SX-F:

thanks Matt!
Hi. By moving the tps does it effect the idling?
What motor?
@Matt South mines a ktm 350excf 2022. Its idling at 0.54
@@neilb2593 Adjusting the TPS is going to change the fueling. That change in fueling may change the idle speed a little bit, but it shouldn't be a major change unless you make a really big adjustment. Adjusting the idle screw on that motor will change the TPS reading because the idle screw actually opens the throttle. Does this help?
@Matt South yeah that helps. Thanks for that cheers
You have about 99% correct BUT unless your bike is producing exactly 5VDC to the TPS your kind of shooting in the dark. Best to send a verifiable voltage to the TPS while doing this.
Thanks for your comment. Please google around and you'll see plenty of posts in message forums (Thumper Talk, ADV Rider, etc..) from the thousands of guys who have used this TPS Tool commenting about how well it works. :) The ECU actually does send an accurate 5V signal to the TPS, this is how the ECU reads the TPS while the motor is running. Also since you're not setting a specific value, but instead you're just going up or down a little to find the best spot, you could technically do it with any voltage as long as it's consistent between readings.
Yes you can assign any value and hunt around for a sweet spot, but the ECU being accurate and the instrument being less accurate you really are hunting and not using discreet information for tuning it. Your tool is worthy of using no doubt helpful, if you want to actually know the voltage going into the TPS and the position reading as a feedback a confirmed 5VDC is needed. Not a theoretical 5VDC or assumption. Take a look at Best Dual Sport bikes website he explains it best.
That guy has a financial interest in trying to convince people that an external power supply is needed, but I assure you it is not. The bikes ECU provides a perfectly fine 5v.
I realize that this is an old post but the issue is that the ecu puts out an exact 5 volts. If your meter is inaccurate (reads 4.9 instead of 5) then your setting of the TPS will be off because of the meter, not the 5 volt supply. That is what the 3rd wire is for. Make sure your meter reads 5 volts across the 3rd wire to one of the others before starting adjusting. One wire should read 5 volts and the other will read 4.4 volts or so.
Sir nissan moco tp sensor aidle potion ?
Thank you for your comment. Unfortunately I am not familiar with that motor and don't have any information to share about it.
Handy! Will it work with any F.I. KTM? Have messaged you...
I'm going to say yes I think it will work for other models that use the same plug. Pop the plug off of your TPS and compare it to the plug in my video (FF to the part where I pull the plug off and show it to the camera at about 1:20). If the plug looks the same then it should work. I make and sell these so let me know if the plugs seem to match and you want to give one a try. :)
How much do you sell this for, I'm interested..

+Matt South I've sent you a email ,looking forward for a reply .
does this work for a 2012 350xcfw
Yes it does. But be aware that since the XCF-W does not have a key, you would need to bump the start button to power up the TPS for about 8 seconds at a time. Or you could just let the motor idle to keep the TPS powered up. Or the most convenient option is the Pro Powered meter, which powers the TPS for you. This video shows you how to adjust a non-keyed bike. It shows a 350SX, the TPS on your bike will be much easier to access but the adjustment will work the same way. The video shows both the pigtail and the powered meter: th-cam.com/video/v1OXY5_jAv4/w-d-xo.html
@@8180634 okay I need to try some things I'm having a problem with the bike starting so I'm just looking for a few things that I can check when ... and whenever I bought it the guy was running it with the idle set very high so I was trying to figure out how to adjust do I have absolutely need to have that voltmeter to or can I just do trial and error without it lol
@@tjdukes7452 You "can" trial and error, but your odds are not very good. Check out the video I linked and you'll see how sensitive it is, then decide if you want to try to free hand it. Also I think spec idle on that bike is around 2000rpm, plus or minus a few (check the manual), so grab a tach and set it right as that can help a lot. The cheap hour meters from Amazon often come with a tach option. Also check the valves as valves that are too tight can really affect starting and idle a lot, actually I would check the valves first. If it kick starts really easily but the e-start doesn't work well then check out the torque limiter on the starter too, there are videos online about that.
@@8180634 the bike kick-starts very easy the easy start button only works every once in it's to the point now where I think my battery is dead because all it does is click one time the fuel pump doesn't even turn over now
@@tjdukes7452 If you suspect your battery then definitely try that first as it's quick and easy. Jump it from your car if you have cables and that might help answer the question right away.
