At pinit racing we've finally figured out the correct porting changes on the 300 TBI cylinders. This SX cylinder gained a lot of power, just fixing the casting problems. Thing is, if you don't know what you are doing and have the right tools to cut the nikasil plating, you will quickly ruin your engine. So trust the one that knows. Also a gain on the 125/150 and 250 https://www.pinitracing.com

The injectors for the 300 SX /XC have changed between 2023 and 2024-26. Also the SX / XC injectors are quite different than the XCW injectors. You must use an ecu programmed for that particular injector or you'll wish you did https://www.pinitracing.com

The KTM 300 SX top end on the XCW bottom may be the best GNCC or faster off-road set up there is. It now has TONS of power, but also has strong bottom end and a high output stator. The larger flywheel adds chuggability to it and it's not so aggressive in the midrange. This build is with all Pinit Racing products and Pinit ECU reprogramming for the 300 XCW: - Oil pump delete and running at 40:1 with Klutz R 50 oil - 91 octane Shell brand premium pump gas with ethanol - Crankcase pressure sensor holder - Fuel rail - Reed stops and reeds - TBI Grunt exhaust manifold - Oversized exhaust cover - Big BS-Li 02 max battery We used the KTM base gasket ending in 80, the Vertex piston from Pinit racing with the intake skirt cut for clearance, the stock 300 sx head insert and BR7 eix spark plug. Plug and piston can be purchased from Pinit Racing https://www.pinitracing.com The best in the biz for the KTM 300

The 25-26 TM 300 Fl is now worth buyng from https://thetmdude.com. It's only sold with all these mods done. It now has crisp, strong power throughout.
