Two Stroke Performance KTM Power Kit - Revisited Two Stroke Performance KTM Power Kit - Revisited Products Provided By Slavens Racing Products Provided By Slavens Racing By Kurt Flachbart By Kurt Flachbart 28 Trail Rider www.TrailRider.com Every now and then, a new product is introduced that not only does what it claims to do, but also de- livers and proves its worth over me. When consid- ering such products, the Two Stroke Performance ECU Reflash Module is at the top of the list. With so many more Austrian TBI bikes sold since we ini ally featured the TSP ERM and associated components back in 2024, we thought it was high me to revisit this cool tool. I'll do my best to explain the need, func ons, and what the TSP ERM has to offer those who own an Austrian TBI two-stroke. Now, some might say, "Why do I need to spend even more money to make my 12,000 dollar dirt bike run properly?" The fact remains that today's fuel-injected off-road motorcycles are somewhat of a compromise, as although the manufacturer knows the bike will be shipped to the US, they have no idea where it will end up, so the tune is sort of a one-size-fits-all scenario. As for the Austrian brands, gone are the days of swapping out pilot jets, main jets, needles and slides. All the tuning is now done through the Electronic Control Unit, or ECU for short. Like most older dudes, I'll admit to being more than a bit technically challenged. With some help from our friends at Slavens Racing, I learned how to adjust the mapping, fuel, and igni on with my first introduc on to EFI tuning with a GET system on my 2019 300 XC-W. Surprisingly, I warmed up to the process, and now that I'm familiar with it, tuning is accomplished much faster than pulling the slide for needle adjustments and dropping the bowl for jet changes. In the end, I found the learning curve to be fun and exci ng. This par cular feature began not long a er I'd bought a new '24 KTM 300 XC-W. I found myself riding my "Comfy Old Shoe," the '19 300 with the GET system, more than the '24 model, as it was just so well-dialed-in performance-wise compared to my TBI model. Basically, the '24 TBI 300 felt a bit numb and blubbery down low compared to my clean running, modified '19 model. While discuss- ing my op ons with Alec at Slavens, he suggested the Two Stroke Performance ERM (ECU Reflash Module), Oversize Powervalve Cover, and Medium Compression Cylinder Head. "Let's do it," I said,
