2018 KTM 300cc XCW Carb and Head Review
The TSP Keihin Carb and High Compression Head work great on my 300cc XCW. Much better than the stock Mikuni. Power band is smooth and just keeps pulling, amazing. Raced 60 miles last week in the Nevada desert of which 10 miles was frozen ground, ice, snow. Kept it on 2 wheels on the ice and was able to pull hard on the dry dirt. Very strong and useable power. Will buy more products from SBM.
This could get expensive!!
Just got back from racing. My kids first race ever.
He placed 5th overall in the 250 beginners class. In reality he was 2nd. 1-3 were sandbagging the class They rode several levels up also and played towards the top. He’s beyond happy with how his bike is running. Absolutely ripping. He was pulling on 250f’s. Once we get the photos back he’s going to do a full review on the TPI page and tag you guys and TSP. This could get expensive!! Thanks again.
Second hand Bike???
Just got myself the newest bike I have ever Had!! A Husqvarna TE 300 2021. I have a 2004 EXC 250 KTM.
The Husqvarna has no paperwork with it Except the registration documents. IT has a Performance Ecu And Head installed. I have taken the bike apart for inspection before I ride it. Sent the information to Steve regarding the identification of the head. He has spent time and effort to tell me the type installed on the bike and its a medium compression. I am thanking them for the super fast response for the information as I did not buy the parts from them. But I will be back.
Installed the low compression head and ecu flash. Tremendous improvement. The power is incredibly smooth on my 250. Before the flash and head, the power would surge a lot. Best improvement I’ve made to myRead more “Major Improvement”

Follow-up on Fine Tuning My Bike
I just wanted to follow-up on all of your latest recommendations for fine tuning my bike: Rekluse: Set Bevel Spring to #3 (stiffest setting) and set to Low Engagement Installed Idle screw and set to 600MV Bike runs even better and no more stalling issues. Thank you again for all of your time andRead more “Follow-up on Fine Tuning My Bike”
Fucking awesome 👏 TSPRead more “Fucking awesome”
Three of these Huskies have your products installed! At the creek atRead more “”
Just wanted to drop you a line and give you some feedback. We talked a couple of weeks ago about my ongoing issues even after head and reflash. My TPS setting was over 700 mV so I turned it down to 600 which I found too low and problems still persisted anyways. Then I tried switching the CCP and barometric sensors. Winner, winner, chicken dinner. This bike has not run properly right from brand new but finally it does. If you have access to CCP sensors I would like to order one. Let me know and thank you very much for your assistance the bike runs amazing.
Thanks for getting the kit back so quick! I put it on and have hit our little short course a few times in the nearby woods with it. It’s great. So much smoother than stock. It really pulls great down low in the rpms now. You can use the whole gear. It’s more fun around townRead more “”
I usually don’t write emails like this, but wanted to thank you for your power kit for my 2019 KTM 300xcw-tpi. Immediately after install, the bike ran the way it should have from the factory. I’ve spent two years messing with it trying to get it to run well and it finally does. The splutter and garble is gone at part throttle, the bike transitions on to the pipe smoothly, and it makes more useable power across the whole power band. Steve, thank you for chatting with me over the phone on the weekend and answering my questions, much appreciated.
2021 GasGas EX300 South Bay Moto Performance/TSP Power Kit First Ride
I received the kit yesterday afternoon and installed it right away, thank you for the immediate turnaround! I thought I’d give you a quick “first ride” impression/review.
2021 GasGas EX300 South Bay Moto Performance/TSP Power Kit First Ride
I warmed the bike up and took it for a quick test/setup ride. You were right, the difference was immediately noticeable! Better pull from down low and a MUCH smoother transition into the mid-range. Now I can easily do low speed balance point wheelies and not worry about getting hit with that sudden mid-range surge that was there before (when I would occasionally get up into the rpm’s a bit). So much easier to control (and safer) and it sounds much better now too! Like it’s crisp and well-tuned. I played with the air screw settings as suggested in the kit but ended up with it back at its original position of 3.5 turns out. That’s where it seemed to run best off idle and at low throttle settings; maybe it’s because I’m at about 4750 feet above sea level here. I couldn’t tell any real difference between air screw settings at higher throttle openings. The idle speed at this air screw setting was basically perfect at about 1470 rpm, so I haven’t installed the idle screw modification yet. We’ll see if I decide I want/need to install it after running at other elevations, but the stock idle setting seems fine for here so far.
Anyway, I’m super happy with the kit so far and can’t wait to get it out into some terrain for a more thorough impression in varied conditions.
50 miles yesterday on medium to hard and tight single track. No stalling problem and bike will now pull from low down and I can carry a higher gear. PrettyRead more “”

Super pumped for the upcoming race season.
Wanted to thank you for all the help on the phone the other day with the “power valve flutter” I was experiencing in the mid range under load (primarily in the snow). Adjusted power valve to about a millimeter from flush, slightly less than it was stock completely solved the issue. TE300i, medium comp head, air screw .5 turns, idle screw installed after a couple rides. The bike is running fantastic, most dialed in 300 motor I’ve ever ridden. Super pumped for the upcoming race season. You should have a few eager customers heading your way soon.
Great Kit, Great Setup! Thanks Again!
Got the bike out a few times since the install and man oh man I am stoked.. The power band is exactly as I wanted from the bike since day 1 … We ride a lot of trials bikes around here and the off-idle torque feels like my trials bike which is amazing.
I’ll be sending more customers your way as soon as they get to try my bike … Even though it’s sled season I’ve been going out and riding my bike a lot!
Got 2.4 Hours on the bike today with no bog once warmed up the bike runs amazing! It won’t stall haha just when you expect it to stall like my YZ250X it lugs 2nd gear up rocky rutted hills it’s crazy!!!! The engine screams too, pull is so linear I love it. I know exactly what the bike will do every time I twist which is very comforting in the tight stuff.
Thanks for everything I’m thrilled with the bike performance it made an already amazing machine even better!
Finally got a chance to ride this past weekend. All I can say is wow, it’s a completely different bike. I haven’t even adjusted the power valve yet and it already is way more rideable in the woods. I can pull 3rd gear again like on my 2018. ThanksRead more “”

Regarding my High Compression Head/ ECU Reflash for my 2020 TE250i
The bike fired up nicely after I installed the head, sounded amazing and throttle response felt really good (clean/crisp). So I took it for a ride yesterday.
Everything is snow covered here, anywhere from about 2-45cm (1-18″) depending on drifts. We run Mitas Trelleborg tires (or grip studs) for the winter. It wasn’t that cold yesterday, about -15° C (5° F) when we started. The bike fired up and idled instantly. There was clearly more smoke from the exhaust until it warmed up, then the smoking was minimal (I’m currently running Motul 710).
What I noticed was that the bike is much more luggable, like my prior TE300i. I see why TSP shows partial throttle readings on the dyno chart. Most of my riding is now achievable in the 1/4 throttle range with some transitions to 1/2 throttle. I only needed to go beyond 1/2 throttle on long steep hills. The bike felt much more controllable and seemed to have a lot more tractable power since I could run 1-2 gears higher at a lower rpm. Previously, low rpm riding involved a lot more clutch slipping/feathering and sometimes stalling.
While I can’t do high speed riding in the snow, I’m looking forward to seeing what the bike is like opened up. It hasn’t lost the quick revving feeling of a 250 (which is something I didn’t like about the 300).
Now the bike seems to perform like it should! I’m very impressed. Having ridden high compression/shaved heads on carbureted bikes, I wasn’t sure if I should expect more of a blast of power like an older 2T MX bike built for speed, not something as suitable for enduro. Clearly the TSP guys know what they are doing with the mapping.
Thank you for supplying the head/ecu flash and the fast turn around and shipping!
I’m sharing my positive experience with everyone
I absolutely love the kit. It runs better all around and I don’t think I’ll ever need to mess with the power again. Appreciate the quickRead more “”
