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
@TokyoOffroad3 жыл бұрын
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...

OK now this is the LAZY BOY option. I didn't want to tear my brand new 2 week old 2021 Husky 300 TPI down so this is what I did. First I removed the single retaining screw and popped off the throttle cover (I did not need to remove the exhaust to do this, I just GENTLY pushed it from the OTHER SIDE on it's edge at the top with a broad bladed screw driver and it popped off). Secondly I could see the blue Locktite on the screw and I sprayed it 4 times with ordinary DISC BRAKE CLEANER, 30 minutes apart, and left it overnight. Next day all visible blue Loctite was gone, an encouraging sign, but I knew that some would still be active in the threaded section of the housing. I then removed a 2.5 Allen/hex from a folding bicycle Allen tool set which have those big loops at the end when you take them out of the set (the loop is critical for leverage, a standard Allen wrench will not work) I then fitted that to the idle screw and once in place, used a bigger Allen wrench handle through the loop in the 2.5 as a lever (any handy short lever would do just as well).Very slowly I kept pressure on it but TIGHTENING it, not UNDOING it. ( So many people go wrong trying to loosen reluctant engine setting screws, tighten them first whenever it is possible because the wrench is being pushed in, much less chance of stripping the hex). Just as the 2.5 Allen started to twist a little under strain, it gradually turned the idle screw a fraction so I stopped and warmed the engine to full operating temp. Whilst doing that I plugged in my OB2 diagnostic unit (dirt cheap on Ebay but get the convertor plug made in England by Lonelec to connect to KTM/Husky) and via my mobile on the free OB2 App, watched the ECU rev count NOT the ENGINE rev count because that fluctuates too much on a 2 stroke, the ECU RPM count is the AVERAGE reading and THAT is the one to set your idle by if you have the choice to do so. It is is easier to get the really fine adjustment on a 2 stroke this way. After much experimenting on my bike I found 1775 ECU RPM (easy number for you Yanks to remember! My Husky must be a Republican!) to be the optimum for my bike with the Air Bypass Screw totally SHUT. There is ZERO reason for using the air bypass screw, it is ONLY there because manufacturers cannot use any other method to adjust idle without effecting emissions. It is a total bodge because the TPS has not been moved so the ECU has not been 'informed' of a change. That is why despite raising the idle speed you get 'flame outs". My bike used to do it all the time and always in the worst situations which caused me to fall off several times on steep hill climbs etc. The Air By Pass bodge works kind of OK on cars and even to some extent most 4 strokes but the 'work around' was never intended for high performance 2 strokes which have totally different "needs" to deliver optimum power delivery characteristics. Trust me, just screw the stupid POS Air By Pass SHUT and experiment with getting a perfect setting with the idle screw which moves the TPS and 'informs' the ECU to adjust the mixture accordingly Your bike might vary on it's perfect RPM average but now mine pulls really cleanly off the bottom (quite critical on the RPM reading I found, higher or lower RPM settings were not optimum) and is NOW great at ultra low speed manoeuvres like "figure of 8" at walking pace, but also goes like a f**cking missile when cracked open. Honestly, it is like riding a totally different bike.The first time I gave it a whiff of throttle the front wheel came up so fast in a power wheelie that I nearly fell off, I just wasn't expecting that much sudden performance increase from fiddling with an idle screw! Lastly, remember to drill a little hole in the plastic cover before you put it back so you can adjust the Idle screw without removing it. I will get around to replacing the Idle screw with a 5 X 50 mm next time I am in a hardware store ( I am certainly not paying $35 for one! 10 cents and an old spring from a Beretta shotgun more like!) but for now I haven't bothered as I don't want to disturb my perfect setting and there seems to be enough Loctite still on the screw to prevent it unscrewing in service. i.e. the idle adjustment is quite stiff in both directions which is perfect. So guys, that is a lazy-arsed Brits way of achieving exactly the same result with 10 per cent of the effort. No heat, no rebooting the oil pump or anything. And if you do get it WRONG and strip the hex head you are no worse off because you were going to strip the entire bloody bike down anyway, in which case you can release the screw with a pair or pliers once you have melted the Loctite. Worth trying! Less hassle, more riding time!

Lesson learned when I attempted to do this idle screw mod... the wimpy little butane torches just don't cut it. Once I switched to using the MAP-gas torch, 30s or so with the flame "broke" the loktite. Now to get out on the trail and set the air-screw.

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...

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:)

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
@TokyoOffroad3 жыл бұрын
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...

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.

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.

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
@TokyoOffroad3 жыл бұрын
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.

Hi mate ive got a te 300 2020 and have done the idle screw mod,but i cant seem to stop idle hanging.ive adjusted air screw pretty much in and out..do you have to move the air screw in milimetre movements
@TokyoOffroad3 жыл бұрын
Did the bike have hanging idle before the mod? Hanging idle indicates that it's running lean. First check that the throttle body hose clamps are secured correctly and there are no air leaks (particularly on the reed valve side). If you also removed the reed valve while you were doing the mod (to inspect the reeds) check that the gaskets are good and sealing with no air leaks and the reed valve screws are secured and torqued to spec. If you don't have any air leaks then check where the throttle body air screw is set. The stock setting is often about 3.5 turns out from full in. Set it to 0.5 turn out from full in and see how it runs. Turning the throttle body air screw out (anti-clockwise) will increase the amount of air which can bypass the throttle body butterfly and lean out the idle mixture. Turning the throttle body air screw in (clockwise) will reduce the amount of air and richen the idle mixture making hanging idle less likely.

@TokyoOffroad3 жыл бұрын
If you've done the idle screw mod and are sure it's a rich spot then try opening airscrew on the throttle body in 1/4 turn increments and see if it helps. The idle will probably go up so you'll need to also adjust the throttle stop screw which you put in. Or if you have an aftermarket ECU you could adjust the fueling. With the GET ECU and WiFi option you can adjust the fueling (and ignition) using the smartphone app while out riding. Really handy... Or a lower cost solution is a Dobeck piggy-back fueling controller which also allows for adjustment of the fueling.

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.
