Sick man! That is what I like to hear. We will be doing a long term review and revisiting soon as well as getting the Husky dialed with the adjuster from tpstool.com Thanks for the sub!

Oregon Dual Sport so an update from me after a couple ride on the dirt and street: the bike has performed amazingly. The power is amazing and can easily get through any obstacle. I had some popping despite the duck tape, but that’s because of a shotty job on my part. I ordered the ball bearing from KTM and husky and haven’t had any problems. Overall, I say it’s a must do for any serious dual sport rider.

taffyboy07 I thought the exact same thing 😅

I went back and stop the video to play that part about five times

What truck? At no point in this video is a bike loaded or unload from any truck?

Mark Yedlicka 3:40 tf is that then

@@gazmgow622 not sure how the hell I missed that, wish he explained the trick of getting the bike out so easy without a ramp

Glock Shooter308 glad to hear it!

When you pulled the reeds did you put something back in it?

You can simply pull the Reed valve piece. I installed an intake tube from ktmhusky.com. The length of the tube can affect air intake. Think velocity stack on your V-8 hot rod.

Robbo Robinson Hard Enduro-Media That’s awesome. In the US there are laws that prevent a dealership from hooking the customer up like that. My dealer told me all about it, but couldn’t actually prep the bike like that legally.

@@OregonDualSport you can also replace the air filter cage for the 2-stroke one without the mesh and get a fireproof air filter (just in case) and you'll see major improvement to the bike, specially snap and low end. That's the very first thing I do to all my bikes here in Portugal.

Did you still add more fuel to the machine after doing so? Or just run without the screen?

@@OregonDualSport I did adjust the TPS after removing the screens so the bike would run richer. I also did a smog delete but I still have the reed valves in.

​@@advsquared Nice! Good call!

Depending on the bike like a 2015 suzuki dr200s that uses a vacuum like you said, when you go up in jetting stages they recommend just taking the lid off :)

It was proved on the dyno that it makes 0 difference.

RideWithWill I recently did a demo day here in Australia and tested the 250 excf, the 300 tpi and the 350 excf and ended up going the 350-definitely haven’t regretted my decision!!

@@50wgpr1 ya man same here! test road the 300 tpi and 350 as well. I really like how easy and predictable the EXCF are! seems like it would be best in technical trail lol

@@RWWRENTAL 250 exc 2 stroke non tpi is best choise

@@scyra9997 Maybe just for your ride style

@@scyra9997 the more I ride 2 strokes the more I want one. tbh they are much more fun than 4 strokes ha ha! I am starting to agree with you!

there is a trick i found for TPS tuning here is the link he uses a phone charger and cord for the 5 volt reference voltage. im gunna try tomorrow forums.rmdra.com/viewtopic.php?t=12067

@@TheTT124564 Top Tip, they have some great ideas, thanks!

Ps, I’d recommend some radiator guards. Trust me, they are much harder to put on after the rad is bent to poop 😳

@@jasonf7063 Definitely pick up the intake tube, they increase the velocity of the air going into the intake due to the size being smaller and the Mototerre ones have a twist in them which increases that. Leaving it open would affect the velocity of the air and it may not be as responsive as it could be. Also, the spark arrestor on the stock end cap is massive and still restrictive even with the screen cut out of the tip. The aftermarket tips definitely have more flow to them.

i have an fe501 with a jd tuner and they recomend just pulling reeds and leaving it how it is.

I heard the same thing on my china bike Enduro. She said it's brand new why are you changing exhaust and putting racing carb. Opened air box also by removing some restrictions on the rubber. My 150cc is now at least 2 HP more. You can feel the power increase. New spokes, new o-ring chain and spokits. Went from 10.2 HP to at least 12 HP. It's alot faster now. But girls cannot understand that. I drive a Yamaha for in town riding and with her on the back. She hates how high the china bike is off the ground.

and save 70 bucks

someone started the myth of the intake boot collapsing without the reeds. it's bullshit.

Thanks! Yes, it has definitely held up. I have no negative things to report after the last few months of use. We will make a long term video on this soon, including the use of TPStool.com's tool instead of the pigtail harness, which is just much more accurate to adjust the TPS than a simple voltage meter.

The vortex is awesome. Totally linear power curve.

John Quest it’s not mistaken. There’s more power here. Ktmandhusky.com has set up this same mod route on a dyno and pulled out about 10hp extra.

They are a waste of $$..

Yes indeed.

Because the throttle body is round would be my guess - Jaren

I wouldn't recommend doing anything to your spark arrestor or packing. It would cause your bike to run lousy unless you did something to control the fuel as well, but even then, I wouldn't take out any of the packing.

I would say in europe, not only in uk

you don't need this. yours is a race bike, like the XCF, so no restrictions.

@@gophop I've heard adjusting the TPS can help with low RPM flame-outs though.

It will not work with a 2021, you’ll want a tuner.

We did one on the Husky, results are the same. These bikes share the same motors - Jaren

@@OregonDualSport thanks Jaren. I'll look into it.

Or put an sx450 factory event bigger intake tight fit but works and had more air flow

Good question! The benefit of the 350 is the feeling of the weight. On paper the 450 and 350 are pretty similar in weight, but the difference in how much the piston moves makes the 350 feel significantly lighter than the 450 due to centrifugal force. You'd be surprised at the difference in weight feeling. The 350 almost feels like a 250. The 350 is built to be more powerful than it comes to us in the US, but emission laws prevent that, so all we are doing here is deleting all those additional components that make the bike run at less-than-normal performance.

Oregon Dual Sport thanks for the response! I agree that on paper they are very similar in weight, I trust that they must feel very different and lighter to ride then the bigger 500. I’ve never ridden any bike like this before so I appreciate all the feedback! Favorite place to ride in Oregon?

Moto Snav I so far my favorite place to ride in Oregon is Timber Mountain in Jacksonville OR. Very cool terrain there.

No it's not, it adjusts the position at which the ecu "thinks" the throttle plate is, so if you give it 10% more voltage the ecu believes the lie, that throttle is letting 10% more air in so it injects 10% more fuel to compensate but as the throttle is not really letting in more air, it gets 10% richer. These numbers are an example and in reality 10% more voltage may not be 10% more air due to the angle of the throttle plate but you get the idea. This follows all across the ecu map at all times in a none linear fashion because airflow changes vs. voltage non linearly, depending on throttle angle, which is not ideal, a corrected map would allow for the different volumetric efficiency with less intake and exhaust restriction at higher engine speeds and cam timing etc. A properly corrected map would be richer at the top end as that's when the free breathing is going to have most effect; also you could adjust the ignition timing which would help. All that being said, this mod is no worse than a carburettor which has worked adequately for decades.

Robert Withers I have a brand new ‘19 XC-f muffler if you’re looking for one by chance? Unless you specifically need just the end cap

Ev an the answer is not much that we can tell, still over 80 miles to a tank of trail riding usually - Jaren

The packing that looks like hair? I cut out a little bit just to be able to fit the new end cap on, but not too much. You definitely want to keep as much as you can. -Alex

You used to be able to do that, but US dealers wont do that anymore and the new ECUs cannot be flashed from what I understand.

@@OregonDualSport Ohhh ok :/

So I took my 2019 KTM 350 EXCF into a mechanic had them pull all the emissions crap off, put on a FMF muffler thinking that now all I have to do is have it mapped... Wrong the ecu is locked, no one can map it and now I'm screwed with having the bike run lean. A few flame outs, sometimes coughs, and an occasional backfire. I ran race gas 1 gal to 1. Whatever is left and it clears up all the problems. So in other words I'm now left with that choice or I buy the vortex. But I plugged in a buddies Vortex for a min and my kill toggle switch that these bikes come with wont shut off the bike. The key works with turning off but as we all know this is not ideal. The bike runs fine but I personally can not run the bike without my off switch working. Anyone have another fix for this?

@@heatherschaefer820 When you 1st install a Vortex hit the start button and kill switch at the same time with the throttle closed.. Repeat this process with the throttle wide open. This sets the tps. This may fix your problem.. Or your kill switch isn't grounding properly ??

Donpablo007 Franko it’s an enduro bike

True, you could have just got a 500

the 350 has lower rotating mass, meaning it feels lighter. So if you can squeeze some power out of it, you get the benefit of that power without the rotating mass of a 450 or 500.

@@OregonDualSport If the 350 has less rotating mass, why doesn't it weigh less?

@@user-sp8eb6iz7f There is a difference between rotating mass and overall weight. A larger piston requires a larger counterbalance.

Baffle in the exhaust broke and was causing huge restrictions at varying rpms.

Austin Schweich I had an issue similar. Bought a 2019 350exc on 10/05/19, was very sluggish and lean. Wouldn’t run right and would constantly flame out. Brought it back to the dealer and turns out the fuel pump was bad. It only was putting out 20psi instead of 60. Got it back and it runs perfect now.

The difference is only about $500 or so - Jaren

yep, just get the ktm 500, cheapest of all upgrade from 350

@@andrewcannon587 That's what l did. 350's are slow as if you come from racing mx bikes. 500's all the way

;)

@@OregonDualSport One of my top 3 places in the World.

For a dusty high desert climate I recon the bike is relatively clean hahaha

rlloft84 I know there are better ways to do this, but I’m definitely not complaining about the extra power I’m getting out of this now... fuel/air ratio in a safe range through all rpms.

Countless good results from tuning the TPS; the testimonials at TPSTool.com are real, and the link on that same page will take you to the thread on ThumperTalk where you can see even more good results. Google around, lots and lots of happy riders after TPS adjustment, all over the world.

We would have had to change the title to "Most expensive way" had we done that.

Did you try it?

Ha, you're right. You get the idea though.

he was talking about TPS supply voltage, not the output from TPS

@@gophop the input is directly proportional to the output after you factor in the resistance of the potentiometer ...... the input on a 350 excf is 5.0v exactly not 6 not 4 .... the output voltage is between 0,5 to 4,6 depending on the setting

500 is cool for more open areas where you can really let it rip, but the 350 is superior in tight and technical trails.

I would agree I own a 500 and was thinking of getting a 350 for that very reason but on paper there’s only a 3 pound difference I guess I really need to try one

@@FATBIKEMIKE the weight difference on paper is small, but how it actually feels to ride is much different. Has more to do with the forces the larger motor creates that make it feel less nimble. But yeah man, you should definitely try one and see!
