  • Hi. What is the correct turn on the air screw?

  • You never disappoint, great detailed video as always.

  • If you adjust the throttle stop screw to adjust the idle and then recalibrate the the TPS as you suggest all you have achieved is give it more air and know more fuel which would be know different from adjusting the air screw like ktm suggest. You should also inform every one that when you do this mod and then take you bike Back the the ktm dealer for a map update that it fucks up the TPS setting as the TPS will be zeroed with the butterfly in the wrong position then making it a pain in the arse to recalibrate it all back up.

    • @J12 Racing - But I'm not cutting fueling back, I've added fuel to the map in the idle rpm range. The TPS cal function sets the idle value, but you can still add (or take away) fuel in that cell. Customization of the fuel map cell rpm upper and lower ranges is also possible. So it is absolutely possible to tune your fueling at idle.

    • @Tokyo Offroad I’m well aware how the get works with the fuelling but if you adjust the throttle stop with your adjuster you’ve basically just holding the throttle open 3-4 % open if you then recalibrate your TPS like you did your zeroing it with the butterfly open 3-4% but then cut the fuel back to start up fueling all you have is an increase in air flow through the butterfly instead of the air bypass valve which you turn in and close off so you have gained nothing. The get doesn’t allow you to adjust fueling at start up.

    • @J12 Racing - I'm using a GET ECU with map by Harris Performance. You can add up to 30% more fuel, or 10% less fuel using the GET app. I'm not using the stock ECU so it's not going back to the dealer for mapping updates.

      Tokyo OffroadTokyo OffroadUukausi sitten
    • @Tokyo Offroad I would like to see how you adjust to give it more fuel after you recalibrate TPS with throttle stop adjusted. It still doesn’t alter the point that you inform people to adjust throttle stops with standard ecu. Then they bring there bike in for mapping updates and it fucks up the calibration of the TPS

      J12 RacingJ12 RacingUukausi sitten
    • No, because you can add more fuel using the GET app. You can't do this with a stock ECU. Thus you have control of the fuel, air and throttle stop position and are still able to set the TPS start cal correctly.

  • My 2020 Hva300TPI idled fine when it was new, about 30-40h in the idle is terrible. Stalls easily and wont idle at all with any gear in. Must try this fix.

  • Question - You said it runs better a little rich off the bottom but after you installed the idle screw you had the air/fuel screw set one turn out (richer) then said it ran better a half turn out from there (leaner). Am I understanding the rich/lean direction of the A/F screw? Not much information out there regarding the TPI A/F screw... Thanks

    CrazystuffyouseeCrazystuffyouseeUukausi sitten
    • @Tokyo Offroad - Thank you. My mistake, I thought you said you added a half turn but after re-watching I see you reduced the A/F screw by half turn.

      CrazystuffyouseeCrazystuffyouseeUukausi sitten
    • The screw controls the amount of air which can bypass the butterfly. The more you open the screw the leaner it becomes. One turn out is leaner than half a turn out.

  • Love your channel and we are on the same journey together with mine being on the 21 300 xcw. What are you thinking for suspension mods for your bike out of curiosity? I am about 20 hrs in and am currently waiting on my suspension back from Protune in OH. I went with the WP 6500 pro fork cartridges and a k tech bladder system for the shock, so pretty excited to get a ride in once up and running again:). I will definitely do the RK Tek head next, but I am a bit hesitant to jump into ECU changes or the idle screw mod. So far the bike has been flawless stock motor wise(stock suspension was fairly decent as well tbh). I ran a slavens s3 on my 16 Beta RR and it really woke the bike up (gear higher riding due to gains in the low end). I will likely be lazy and just swap to the RK head unless the bike starts giving me trouble or needs further tuning. I am not very mechanically inclined so god help me if the motor starts needing substantial tuning changes:)

  • Could you please check if this Mod is really needed? My dealer told me that 2020 models don´t need this mode. If you adjust idle with idle speed adjusting screw, the ECU find that the RPM is higher and the ECU adds more fuel. It is not lean anymore.

  • Is TPI really better than a carburetor ?? Seems to make things complicated.

    John FavreJohn Favre3 kuukautta sitten
    • That's not an easy question to answer. I still have carb bikes and love riding them. There are pros and cons for TPI (and carb bikes). Yes, the TPI system is more complicated than a carb bike. TPI bikes are able to compensate for elevation and weather changes and have oil injection (premix not required). Carb bikes are simpler (usually easier to debug if there's a problem) and can perform well if the rider has a good understanding of how the carburetor functions and can tune it.

  • just FYI you only need to do the oil prime when replacing the pump. as the pump still has oil in when doing this mod you dont need to prime it. manual says pump replacement at 80hrs, mine did 280hrs just replaced it recently. theres a lot of variation though, some bikes have been failing at 20-50hrs. The tell tale sign is your bike will foul plug on start up. What is happening is the seal inside the pump fails and while your bike is sitting in the shed waiting for next weekend the oil seeps into the inlet and when you start your bike it sucks it all down and fouls up

    doublehelix109doublehelix1093 kuukautta sitten
    • Yes, absolutely prime the pump if replacing it. But I think it a very good idea to purge air from the oil hose too after completing a job like this if the hose has been removed and you can see air in it.. Good information regarding the early warning signs of a failing oil pump seal...

  • You have a very good channel and your info given is spot on. I have a question if you don’t mind. I have a 2020 250 tpi with 40 hours on it. I started adjusting the powervalve out, bike is running fantastic but oil has started to come out the back of the exhaust. Is there a relation between powervalve adjustment and running rich, or should I turn the air screw in to make it run leaner, I know there could be a 100 different answers, but tell me your first thought that comes to mind... great channel....thanks

    • @Tokyo Offroad thanks for the feedback, much appreciated...

      Gordon Smith SAGordon Smith SA3 kuukautta sitten
    • If the bike runs well and you like how it feels I wouldn't worry too much about spooge from the exhaust. Excessive spooge may be due to the bike running rich, engine not reaching operating temp, too much oil, or oil being used has a high flash point. Turning out the PV preload adjuster will allow the PV to start opening at a lower RPM. This may result in the bike running leaner. Turning in the throttle body air screw (clockwise) will make the bike run richer and drop the idle as the amount of air which can bypass the butterfly is reduced. If your bike is stock and you're still worried about it I recommend discussing it with your KTM dealer. One issue which can occur is that the oil pump can leak oil when the bike is not being used. This makes it hard to start, or may result in fouled plugs. It may also result in spooge from the silencer...

  • I tried to adjust the idle on my 250 tpi 2020 as they recommended in the manual via the air mixture screw, I’ve now found the spark plug oils up after a while of idle/running and it will not restart, does anyone know how i reset this air mixture screw back to original setting? ( It is now at 6 1/2 turns out from closed)

    TG243TG2433 kuukautta sitten
    • @TG243 The problem is there is no magical setting if I were you I would fully wind the screw in and wind it out 1/4 of a turn out until the bike doesn't stall. also note that to far out is lean and the bike will have a hanging idle

      Sean McintyreSean Mcintyre3 kuukautta sitten

      Drew VDrew V3 kuukautta sitten
    • No, KTM do not recommend changing the PV spring from the stock one (yellow). Changing to the red PV spring may make your bike run lean so be careful. I richened up the fuel map when I changed to the red spring. I much prefer how my bike runs with the red PV spring (stronger power but still very linear), but I know some people don't like it, so it's really personal preference. I think it's worth testing, but just make sure your bike doesn't start running over lean.

  • Mine came with blue lock tight, never needed to heat it to get it turning. Also I just adjusted the factory screw, never changed it for a long one, it will take you a couple of tries but once you set it, it's set for life. PS: Bike is all stock works perfect 😉

    St OneSt One3 kuukautta sitten
    • @Tokyo Offroad I agree with you 100% both on the thread lock and on the screw. If I had seen this video before I done mine I would have done it your way for sure. To stop my screw from moving I did in fact put some lock tight back on it, and it can be a pain in the ass to put it on with out removing the throttle body, so yes I love that screw mode you done 😊 Thank's again for sharing 👍

      St OneSt One3 kuukautta sitten
    • Interesting. When I was looking at the factory set screw the thread lock did look almost blue, but it was a bit darker (purplish). With many reports of people damaging the factory screw I think it's a good idea to use some heat as it can then be removed very easily as shown in the video. Yes, you could continue to use the factory screw, but it may be prone to move, unless some fresh threadlock is applied once you've decided on a new setting. The bolt and spring I used cost less than US$2 and work well so I'm happy with this solution. I know lots of people who ride their TPIs completely stock and that's great if you enjoy it. I think a lot of this is personal preference and how you like the bike to feel...

  • Great video and explanation of setting this up! I would like to get your thoughts on KTM idle/air screw position at varying elevations. I ride at about 8500’, what elevation do you typically ride at and do you think that affects how much the KTM screw should be turned out?

    DavidDavid3 kuukautta sitten
    • @David The factory idle air screw should be closed with this mod which i think is mentioned in jeff slavens video. it serves no purpose as the idle is now controlled by the butterfly as it should be and the mixture is controlled by the ecu.

      doublehelix109doublehelix1093 kuukautta sitten
    • @doublehelix109 that is correct regarding normal operation of the TPI system. The question is specific to the air screw adjustment described in the video. What is being proposed in the video is that by manually adjusting the idle rpm by keeping the throttle/butterfly open a greater amount, the air idle screw can be set in a more rich condition by turning out 1/4 turn from closed vs 2 1/2 turns or whatever would give you the best idle using the factory adjustable method which results in a leaner condition at idle and less bottom end. I suspect that the factory idle/air screw would need to be turned out more than a 1/4 turn to compensate for altitude.

      DavidDavid3 kuukautta sitten
    • Once you have the setting (air screw and idle screw) dialed in to your liking you shouldn't need to change it as the bike will compensate to temp and elevation changes.

    • I would also like to know this. I ride at 7800-10000 ft and I have added this screw. I find now that my 2020 300 tpi will leak nasty oil/fuel out of the Right side engine cover near the exhaust port but ONLY when I adjust the air/idle screw to a richer setting= If I set mine to 4 full turns out and anywhere richer it creates a leaking mess when I ride. I set it at just past 4:25 turns out and it runs great, less spooge. When it is set to be more rich I get the tailpipe spooge as well. Now I run it at 4:25 turns out from he fully closed position. Runs great.
