Thanks for the video! I'm going to try one of these out. I've tried quite a few mods on the 24 250 XCW, and just for fun I swapped the cylinder for an XC/SX version. The porting differences between the cylinders are easy to see and measure, and the XC/SX cylinder moves the power to Mid/High RPMs from the Low/Mid power characteristics that the XCW cylinder is designed to produce. Now the bike revs out like the XC/SX, but the XCW has a heavier flywheel so it's not quite as aggressive. Some other parts have to be changed as well, but I think the porting made the biggest difference in overall power. I can rev it out several seconds longer before it falls off the power, and many times that's enough to prevent the need to shift before the next turn.
Slavens and TPS are both too notch service. I won't go in to detail how well they take care of their customers, but they worked together on a Saturday night up to midnight to get my bike back up and rolling. Now that's customer service a d people who appreciate your business. They are F*ing awesome.
I got the ERM for my 23 250xc and it really made a difference. Pretty surprising. I didn't initially do a powervalve reset, which I should have. When I finally did, the bike is an absolute rocket ship. I really don't see the need in getting the head, I feel like any more power would make it almost unrideable for my skill level.
Just found TH-cam channel. Already subscribed. Picking up my new 2025 Husqvarna TX300 Heritage Edition on 12/3. Already planning on getting the TSP high compression head and ECU reflash and their new bigger power valve cover. I’ve always ran Ethanol Free Super Unleaded mixed with VP race gas at 50:1 in my YZ285. Ethanol Free is way better for 2 stroke top ends. Leaves no varnish buildup in carb bikes 👍
I deal with Alec as well and like you said, he's great to work with. Right now Slavens has the ERM on back order, soon as that lifts I should have mine. Any chance you can do a in-depth vid on the ERM changes you've made and how you found your sweet spot once you get some time under your belt? It's a huge benefit to us when learning from pro riders like yourself - that way we can set up the bike and dial it in perfectly. Man it's great to watch you rip on that thing! Cheers...
I will work on an in-depth one, I'm still tweaking on it but have really just found myself making adjustments to the power valve depending on terrain and available traction.
Tsp have it dialled. Recently installed their medium head, injector relocation and erm on my ec250 and its a different bike. Absolutely love it. Good thing with the tbi bikes is that you dont have to fork out for the injector relocation.
Awesome! I have a TSP medium head and tune on my GasGas 250 TPI and it’s a great upgrade. Interesting that the new XCW line has an electronic power valve
With the ERM, you can detune one of your maps too to better suit sloppy/ slick conditions. And like you said, the power valve adjustment can make a huge difference on the power delivery. One thing i probably would have mentioned is that you were probably using the pro mode which costs $50 additional, but it was well worth the price, IMO. I'm still messing with mine. But actually looking forward to people sharing their setting and comparing them. Any plans on doing the oil injection delete?
Great comment, I do have the pro mode but I started with basic to get an understanding of how things affected the bike first. I don't plan on deleting the oil injection.
In the video, the clip I showed was just to give an idea of what I had to do to remove the head. I didn't swap out any of those parts so still running the Akrapovic Slip-On silencer with the OEM exhaust pipe.
It's from the guys at MotoMinded in Grand Junction, Colorado. I'm running a 2020-2023 XC-W headlight mask with a kit that they sell with a Baja Designed unit that bolts in with three screws. Moto Minded also sells the pigtail that allows the the new plug on the 24 xc-w bikes to work with the older generation lights. The reason I run the old mask is that it gives me enough room to mount up my GPS unit behind the handlebars.
The TSP ERM would for sure give you the ability to get more power and more rideability out of the XC. Good question on the fuel consumption, I haven't noticed much of a change over stock consumption. I notice fuel consumption being much more affected by riding sandy tracks and trail vs. hard pack trail as well as riding race pace vs. trail pace.
I was getting a little over 60 miles comfortably in Idaho recently but wouldn't push it over 65. I was also in a trail ride pace and not being super aggressive.
I have both 24s xcw 300 and xcf 350 and can't decide which one to keep lol both sweet bikes but I like not having to worry about stalling issues on my 300
I have the 350 also and unless you ride the same speed as Cole or you're simply a mere mortal a recluse will fix all your problems. I have both bikes in my garage and my toughest decision is which one do I ride.LOL
Cole, I have a 24 300xcw, have the Standard TSP flash + med head, I want the bike to run more like my TSP '23 300tx , I just got the ERM in ... with that said could you share what changes you made vs the Stock TSP flash within the ERM, you mentioned changing the powervale, how much more did you open it, 10%? and at what RPMs? any changes to fueling/timing -Do I need Pro Mode to get the Powevalve to where you have it? I only have the Basic - Much appreciated
You can increase the PV settings appropriately in the basic mode. I just went up by increments of 1 until I got it where I wanted. Nothing was over +3 but still going to experiment more.
@@ColeKirkpatrick I tune & tested today did, +1% on fuel, + 3% on timing & +10% on PV across all rev/throttle ranges, it feels good, especially on hill climbs
I do have a set of cone valve forks for this bike but at the time of me filming myself with the bike I had sent my pro component suspension off to Solid Performance to get serviced.
Would u say it feels like the 300xc now power wise or still not as explosive? If not Do u think adding the high comp head would have been better to get it closer to xc power/explosive?
I have a ‘23 300 xc and a ‘24 300 xcw. I upgraded the xcw with a tsp high comp head and their ecu reflash. These upgrades are both improvements over the stock and the green map gets u closer to xc type performance. Still, imo, the xc is a straight-up beast and sooo much fun to ride!!! Throttle response is noticeably quicker on the xc and the top end rocks. For me personally, riding more technical single track, the xc isn’t any faster but it’s a blast to ride. If smooth is fast, the xcw is my best bet. My only complaint with the xcw now, is the slower throttle response. It’s negligible for general trail riding but in the slow technical stuff, there’s a little room for improvement.
I've ridden the XC-W platform a lot since 2017 and really enjoy it. It's also the type of bikes that Russell Bobbitt and I use for the Gnarly Routes tours. Our entire fleet of rental bikes are XC-W models so the more time and knowledge I can get on the bike the better.
Isn't that basically what the XC model is? EXC (XC-W in the United States) is for enduro, SX is for motocross and XC is for cross country - think of something like GNCC and NHHA. It's based on the SX and it's not sold outside the United States.

I only just got mine tuned with the same TSP tune and its amazing how much it woke up the bike. ERM is worth every penny in my opinion.
Totally agree!
Just to confirm... Are you saying you used the ERM to load the TSP tune, but didn't do the upgraded head?
@@vonrunnerno I also did the medium head

I got the ERM and the oversized exhaust cover, no head, bike runs great. I’m riding at 6-12k elevations.
Thanks Cole, always appreciate your honesty. I get most all my parts from Slavens, he's a top tier guy for sure. You sold me.
You're welcome, thanks for watching!

Same experience I had with my ‘24 TE. It was a little lazy stock, but the ERM made a huge difference.
@@WASemiHardEnduro Are you saying just the ERM tuning made a big difference by itself, or did you also add a medium or high compression head as well?
@@vonrunnerYes. No head needed.
@@WASemiHardEnduro Good to know, thanks for the info!
Awesome! I have a TSP medium head and tune on my GasGas 250 TPI and it’s a great upgrade. Interesting that the new XCW line has an electronic power valve
All of the TBI version two strokes feature an electronic power valve now.
Excellent video. Thanks! Always great to hear how these bikes can be tuned with some knowledgeable rider input.
Thanks Cole. Very helpful and informative. Btw, the video footage at the end..is this the same property as the Red Canyon Enduro?
It's from my family's place but it's about twenty miles from red canyon so it's very similar terrain.
sorry one more question what are you running for gearing? Im at 13x49

Great content again.
What's the difference in the exhaust that you took that expensive can off and are you running the stock expansion chamber
In the video, the clip I showed was just to give an idea of what I had to do to remove the head. I didn't swap out any of those parts so still running the Akrapovic Slip-On silencer with the OEM exhaust pipe.
Hello, with what ratio of sprockets did you use 13/49?
Hi, how do I can search the headlight set up that you put it to your bike, thanks
It's from the guys at MotoMinded in Grand Junction, Colorado. I'm running a 2020-2023 XC-W headlight mask with a kit that they sell with a Baja Designed unit that bolts in with three screws.

Great video, how have you mounted your trail tech voyager pro?
Hi,
There is a difference of 8 hp between xc and xcw.
Could TSP module increase xc power?
How is the fuel consumption with the TSP module?
The TSP ERM would for sure give you the ability to get more power and more rideability out of the XC. Good question on the fuel consumption, I haven't noticed much of a change over stock consumption. I notice fuel consumption being much more affected by riding sandy tracks and trail vs. hard pack trail as well as riding race pace vs. trail pace.

@williamcrotts7054 it's a hard decision lol
I know the feeling! I'm listing my 350 XC-F for sale this week and already am having second thoughts. They are both great bikes!
@ColeKirkpatrick literally in the same situation and I got the factory Edition too😪
My 350 is gone lol kept the 300. Now adding a 450 xcf-w. Like Cole said I live the xc-w platform and hope I like the 450

@@LetRRoll Thanks for chiming in!
@@LetRRoll Have you tried lighter flywheel?
@@LetRRolldo you have the same throttle tube cam in each bike? The xc comes with shorter throw and the xcw comes with a longer throw.
Why did you choose the xcw instead of the xc?

Anybody detuned a TBI SX motor for enduro? Suspension?
Isn't that basically what the XC model is? EXC (XC-W in the United States) is for enduro, SX is for motocross and XC is for cross country - think of something like GNCC and NHHA. It's based on the SX and it's not sold outside the United States.
The xc is essentially that, they have the same engine and head insert
...or just buy the XC.
