(2021 Update) How to Improve Starting Idling KTM HQV GG 250 300 TPI

[@kennethsimek8707]

just bought the easy idle screw a few days ago and watched up on both of these videos. Thank's for going into such detail on how to do everything, it answers all the questions I didn't even know I had.

[@slaverace1]

You're welcome.

[@hermitrob5481]

Videos never go on too long. The 411 is invaluable. Wish Jeff was my neighbor

[@1122ss]

As always, thanks for the info Jeff. I used CRC chlorinated brake cleaner. It is the RED can! Not the green can. No need to buy the fancy bob smith stuff, and you can always use the brake cleaner for other tasks. The white thread locker dissolved after I soaked it about 3 times over the course of about 3 hours. Worked perfectly. It came right out with a T10 torx bit. Cheers all!

[@hayes831]

i did this on my 2020 300 xcw and also the Coober ECU. WOW it runs so much better. off idle is way better. no more pipe bang, and no more stalling on downhills. super happy with this bike.

[@slaverace1]

Thank you.

[@MC0386]

I just did this to my new 22 xc-w 300. Air screw 1 turn out from flush runs perfect

[@Stolo17]

Heating up the tip of the Allen wrench hot hot and letting it sit in grub screw worked well, plus some additional heat on the outside

[@randerson7761]

Thanks Jeff. I have a 2023 so I'm going to look around a little more, but great info.

[@WyoJoe]

I have a 19' 300 , GET ECU (with Slavens Maps) and Race Kit and found the bike runs great with the air screw 2.5 turns out.

[@prestonthomas9406]

Have the same exact bike and setup. I’ll try it out. Thanks for the info.

[@JeffreyParhamChiropractor]

First off, I want to say this post is not about blaming anyone but rather sharing my experience that hopefully will help others My 2020 KTM 300 xc w has 195 hours and until recently idled good enough to "get by", so I never updated the idle screw. After watching another video that used Uncure on the OEM screw without removing the throttle body, I tried that method but couldn't get the OEM idle screw out even with soaking the screw regularly for 3 days using Uncure. After 3 days still couldn't get the screw out so went riding with some buddies yesterday. Rode up the first hill with a 180-degree turn at the top into a steep downhill. Went into the turn chopped throttle and the bike died, fell downhill landing face-first into rocks. Lost motor control of arms and hands for about 60 seconds, and first thought was ""oh shift this is the big one". Regained control of my arms and hands and my riding buddies helped me get up and walked back to the truck. Went to ER with some weird symptoms in both arms. Diagnosis is contusion of the spinal cord, C3/4 disc HNP, Neck Strain/Sprian, compression fracture at T11. My recommendation is DO NOT put off doing the Idle screw mod with heat per Jeff's video!!!! The good news is that I now time to fix the idle screw and to straighten up my garage before I trip and break a leg!!! Never stop riding!!! Cheers!!!

[@rideroftheweek]

Did the bike die because the OEM screw backed itself out after you soaked it?

[@JeffreyParhamChiropractor]

@@rideroftheweek l have not checked the oem screw yet. I kind of doubt it backed as I only soaked from the top of screw and it was still super tight.

[@JeffreyParhamChiropractor]

@@rideroftheweek Since I’m on the injured list I pulled the throttle body and found the OEM screw has not backedout.

[@carrolls4061]

I used this on my 2019 husky and this works a great 👍🏻 I did have to let it sit over night to get the screw out

[@dylanhughes9279]

Just installed my slavens idle screw. I tryed the debonder overnight with no luck. Heat was the only way to get that old screw out.

[@j.g.7864]

Just finished installing on my 21 GG EC300. Debonder worked fine after two drenchings about two hours apart. Needed to set the gap a little larger than 4.75mm for a nice stable idle, but running great!

[@lostinpa-dadenduro7555]

What did you wind up with for the air screw turns?

[@j.g.7864]

@@lostinpa-dadenduro7555 3 out, if I recall

[@NoPro-dm8xj]

Have you done this on 22-23 models? Are the turns out still around 4?

[@slaverace1]

Yes. The 22-23 models usually end up about 2 1/2 turns out.

[@coltonmcvey7751]

2021 KTM 250xc TPI. About to install idle screw. Bike has 135 hours and notice the idle is starting to seem oddly low. Wish me luck! Is it still recommended that the air bypass screw be between 4-1 1/2 turns out? Thanks for the informative video Jeff

[@slaverace1]

Hello: 4 to 4 1/2 turns out is a good starting point.

[@coltonmcvey7751]

@@slaverace1 Awesome thank you the quick response on a old but great video! Your video got me wanting to do some wrenching so today I tore down the swing arm and linkage and got it all cleaned up and greased! Thanks for the info and always look forward to your videos on the bikes.

[@mschumaker1]

Id like to see a follow up or part 2 of this video showing you adjust the idle with the air screw and idle screw. I know it's same as a carb bike but still

[@slaverace1]

OK, I'll put it in the queue.

[@mschumaker1]

@@slaverace1 Thanks! if you did a video on tuning 2 stroke bikes with the oBD ELM tuner, that would probably be pretty popular too

[@richardhartley7094]

Can you fit this with a oem Ecu my concern is the throttle position sensor being out of sink thanks

[@slaverace1]

Hello Richard: Yes, it works well with the OEM ECU.

[@nevadahardenduro]

Tried the uncure. Let it soak heavily for four days. Wasn’t even close to budging. Ended up pulling out the throttle body and using MAP gas. My grub screw was heavily coated with a white loctite. Maybe some are more heavily coated than others, but I honestly feel that no amount of soaking this would’ve released the screw. Just my experience at least.

[@scottmcguireTC300i]

Awesome info as always Jeff, cheers from Australia

[@teambft1]

Jeff I’ve got your get tuner on a 19 300 tpi and your idle screw. In the get instructions, states AS out 2 to 2 1/2 turns vs your video with stock ECU at closed to 1/2 out. Is this still correct? Thanks

[@davidbiggin6584]

My GET race kit install manual for the 21’ model states the same.

[@slaverace1]

The GET instructions are for the GET base maps, not our custom maps and air screw settings varies from bike to bike. Try 2 to 2 1/2, try 1/2 to 1 turns out, just try different settings until you get the what you want. Stick a screw driver in your pocket, go ride and sort it out. Just takes a few minutes.

[@teambft1]

@@slaverace1 I have and I do. Always good to have a base setting to start from.

[@raulgarciamate8888]

Hi from Spain. since I have put the external idler screw I am able to regulate it to my liking. but the consumption of gasoline has skyrocketed... my question is what is it due to? Could it be that the TPS needs to be adjusted? Thank you for all your teachings and I look forward to your response.

[@slaverace1]

Hello: The idle screw has nothing to do with fuel consumption. If you are using the O.E.M. ECU the TPS does not need re-adjusted.

[@dmorgan3244]

Hi Jeff. I did the idle screw install according to the books, and as part of that measured the factory grub/set screw setting before removing it so that I could install the new idle screw to spec. All good on that front - the install was successful. But since then I have adjusted that screw numerous times and don't know where it is at relative to the factory position. Reviewing some youtube vids now (mainly the one from Two Stroke Performance), I realized that you are really only supposed to adjust that idle if necessary, AFTER having adjusted the bypass screw to where you want it. I want to set it back to the factory default baseline again, without having to remove the throttle body again. I seem to recall that you can take a voltage measurement somewhere and used that to reset it. Does anyone know how I can do that?

[@slaverace1]

The setting is .57 to .63 ohm.

[@SnailzPace]

​@@slaverace1Jeff, shouldn't this be a voltage (DC) measurement, taken between the TPS ground and signal return pins, not ohms?

[@ghost53pilot]

30 seconds of heat it allowed a small turn and then 15 more seconds of heat applied. I then turned it in and out for a few turns and then all the way out with no problem. Just turn it very gentle...if it doesn't move then add more heat.

[@_zolo]

Hi Jeff, all. Stupid question, I know. But isn't the throttle body aluminum? If so, is the upgraded stainless screw going to cause corrosion over time?

[@slaverace1]

Hello: Yes, the body is aluminum and that is why we chose stainless because of it's compatibility with aluminum and lack of corrosion.

[@_zolo]

@@slaverace1 But stainless and aluminum are a recipe for galvanic corrosion, no?

[@slaverace1]

@@_zolo Wrong

[@MikheilZhizhilashvili]

Jeff, Can that mod cause crankshaft bearing damage? I am asking you that because, if from factory bike cames lean mixture and we change and make it rich, that injections will give more fuel and air/oil mix will be the same, so more fuel will go to crankshaft bearing holl and there will be more fuel as air/oil. I think you understand logic what I am asking you. so If you think about that please let me know. Thanks,

[@CharlieTrevaskis]

With transfer port injection not much fuel should be going through bottom end.

[@DMC-179]

@Slavens Racing does this also apply when using the "extreme" or "sports driver" map which is in use? I drive an EC300 2021, so also 4-5 turns out?

[@slaverace1]

It does not matter what map you are using. Set the air screw for best throttle response and performance, not a predetermined setting.

[@DMC-179]

@@slaverace1 thank you. I wasn’t sure because the oil getting out of my exhaust..

[@Lorenzosiciliano]

I own a 2021' EXC 250 TPI the default bypass screw is 2 and 3/4 but my bikes have a tricky pipe bang when I release the accelerator. Should I resolve it with the idle screw mods? How many rounds Do i need to set the bypass screw after the installation of idle screw ? Thank you

[@slaverace1]

Lorenzo, Our idle screw is not a mod, just an adjustable idle screw. It allows you to set the air screw where you need it and that varies from bike to bike. Dive in and get er done.

Tried debonder on my 22 ec300. Soaked for 24 hours with multiple applications. No luck. I’ll keep it for other purposes. There was a hefty amount of loctite so my hopes weren’t high. 10 seconds of heat and it came right out. May work for others tho!

greetings jeff I am writing to you from Latin America ECUADOR. I hope you can help him with a small question about my motorcycle, it is a ktm tpi 2019 250cc and I want to change it to the 300 kit, do you think I will have some problem if I keep the same software of the 250 since here they cannot help me with the reprogramming of the ECU. I appreciate your response.

Hello: The mapping needs updated to the 300 map. All dealers have a computer and software to upgrade the ECU.

[@moterohot]

@@slaverace1 thanks for answering I had a long conversation with the KTM technicians here in Ecuador and they told me that it is impossible to load the software on the 2018 and 2019 tpi models and it took me a terrible disappointment since it can only be done on 2020 models onwards. Now I had the opportunity to put the ecu of a 300tpi 2018 on my 250 2019 motorcycle and it started without any problem, now would you believe if there was some terrible damage to the cylinder with this ecu

Unusual that your `20 runs well at 1 turn out. 2020/21 models have rich O.E.M. mapping and typically need more air.

There is no exact setting for any brand or model. Settings vary from bike to bike. The video is primarily about installing the idle screw, not settings. Dive in and find the sweet spot on your bike.

Hi from Spain. thanks for the great videos. I have a 300 21 and the ideal would be 4 laps from closed? Sorry for my bad English but your videos are subtitled and sometimes it's hard for me to understand everything. It would be incredible to be able to activate the subtitles in Spanish

The ideal setting varies from bike to bike but 4 to 5 turns is where most end up. Thanks for the info about sub-titles. All future videos will allow you to change the sub-titles to Spanish and many other languages. Just click on the tool wheel icon and change to the language of choice.
