Steve is awesome! Super knowledgeable, always willing to help and gives great suggestions/advice.Product is amazing. I’ve got the tuned ECU and the medium comp head.Steve helped with getting the cylinder re-nikasiled on my first rebuilder with piston A, then my most recent he supplied me with Piston size B.I’ll send it back in for Nikasil and another size A piston on the next rebuild.He even threw in an extra O-ring since I damaged the first one my reinstall.Will continue to purchase my rebuild kits through SB Moto.

My 2023 Husky 150TPI bogged under the pipe unless I abused the clutch. When it did hit the power band, it was like all or nothing. I really didn't enjoy riding it. Steve really helped me understand how the ECU re-map and head would help. It was super easy to install (and I'm more of a YouTube mechanic). The bike runs super smooth now. much more linear through the power band and doesn't bog. It has a lot more torque in the low end as well. I wish I would have done this last year!

ALL I can say is I actually LIKE riding my 2025 KTM SX 300 now. WHAT a difference, it runs clean, efficient, throttle response is back to what I expect, and it is FAST. Sorry for the capital letters, I am just super pumped and excited that my bike runs the way it is supposed to. Thanks a million South Bay Performance, and thanks for the One day turnaround!!!!!! A+++++

saved my bike, opened it up Thank you so much!!!!
Sorry, no reviews match your current selections
A necessary upgrade for anyone doing enduro riding.
If you like your bike now, you’ll love it after this. Just buy it. You won’t regret it.
TBI power kit is top notch quality. Its great the kit comes with all new o-rings and washers. The ERM is actually so useful and easy to use.
I should have went with this TSP carburetor from you guys a long time ago
Very please with service and parts from Steve at SBMP! My 150XC-W runs a lot better on the bottom end. Steve was very helpful in answering many of my questions pre- and post install. Thank you SBMP team!
All of the above were received back within a week from sending in my ECU, All parts required for the engine mods were included and installation was straightforward following the install videos.
My bike is a 2022 Gas Gas 250EX, purchased used, with 40 hours on the meter. Owned since April 2025, and has fouled plugs continuously with overly rich fueling from the stock ECU on cold start-ups. Several friends and family have used the TSP/South Bay Kits with great results, no question on following their direction.
After installation, did several cold starts with very moderate rides around the neighborhood. Finally got to due a real ride last weekend. Easy starting, NO plug fouling, greatly improved power delivery throughout entire RPM range with great throttle control and response. Finally, the bike works like what it should have from the factory! I am a very, happy camper.
Thank you very much South Bay Moto,,,,,,Darryl Reid
