EX300 ECU Performance Mapping Testimonial

Hey Dave,

After talking with you on the phone, I sent my 2024 GasGas EX300 ECU for your tune. All of the complaints that I spoke to you about were addressed by the reflash. I took the bike to some fairly open and long trails to wring it out and the missing top end is now there. It no longer noses over early. I've also taken the bike to a local very tough, very technical 5 mile single track loop. There's more power, it's much smoother, and pulls hard from idle in every situation. Actually, It's the first time I have ever completed this single track loop without stalling or falling off a few times. You'd have to be really ham fisted to stall or flame it out.

I also mentioned when we talked that my 2011 KTM 300XC, that has a lot of mods, seemed to pull harder and rev higher than the EX300. The 300XC now feels a little weak in comparison. To say I'm very pleased is an understatement. Also, not that I even worry about it, but for the guys who do worry about spooge, it seems to have cut the amount of spooge in half.

Money back guarantee? I don't think so. It's definitely a keeper.

Thanks much,

George Lewis
KTM 300 XCW cylinder on an XC for 2023-25? The dyno runs, costs and bottom line

KTM 300 XCW cylinder on an XC for 2023-25? The dyno runs, costs and bottom line

We put an XCW cylinder on a 2023-2025 300 XC, and we gained almost 3 foot pounds of torque, and 3 extra horsepower from idle up to 7,000 rpm. The 300 XC already had our TBI Power Bundle mods in place. The bundle includes our TBI Power Mapping, Oversized Exhaust Valve Cover, Billet Crank Case Pressure Sensor Holder, 90 Degree Fuel Rail, Spark Plug and our Power Reed Strips. This Power bundle is available on our website and makes for a great foundation for your build. Then we just switched the cylinder, along with the cylinder head, and put a new piston in it. It also requires a different base gasket. The lower port timing with the XCW cylinder adds that bottom end grunt your looking for. This is the bike that the XC should have been, and you can do this for around $1,000. If you're interested in making this happen, you can get in touch with me, and I will help you get together everything you need including the base gaskets. Before you go there though, we strongly recommend you install our TBI Power Bundle to start. Visit PinitRacing.com

Real world vs Dyno results on the 2023-2025 KTM 300 XC - Power delivery to the dirt is what matters

We're testing out our KTM 300 XC build in Arizona dirt. After all the mods and dyno work, it's time to see how this bike really rides, using just 91 octane gas. Come along for some single track soft enduro riding. We have a spark plug with a 7 heat range, and it looks good after all the riding. This bike had a lower compression head at 178 which worked very well here. We had our reed strips installed, our oversized exhaust valve cover, crank case pressure sensor holder, our aluminum fuel rail, flexible idle screw and an upgraded lithium ion batter. Of course our ECU performance mapping on top of all this made for a much improved experience. This is a great bike for an XC platform if you're racing moto, XS and cross country desert stuff.

Taking Apart TBI Top End - Things to Pay Attention to

Taking Apart TBI Top End - Things to Pay Attention to

When going to rebuild the top end of your KTM / Husky TBI 2-stroke, there are 4 important things to look for, and I will go over each one here: Piston and Cylinder Head Condition - Scratches on the piston is one thing to make note of. We also look for scratches in the cylinder head. The cylinder head scratches can be cleaned up with a ball hone hand drill attachment if you have one handy. You can replace the piston if the scratches are bad. In our instance, they don't look bad, so will leave as is. Condition of Piston Ring - I also look at the piston ring as well, making sure the face of the ring has been cut in properly. It should look shiny and flat all thew ay down the face. This means it's broken in properly and seating fully. Sometimes synthetic oil can prevent the ring from wearing in properly, requiring a shift to petroleum based oil until it does. I use legend oil which is half petroleum and half synthetic. You can also use tech break in oil. Then you can switch back to fancy synthetic oil after. As your rings wear in, your compression should go up. Cylinder Base Gasket - Cylinder base gasket is worth taking a good look at as well. The TBI bikes don't come with sealant on the gaskets. I use clear RTV silicon on a fresh gasket during the rebuild for a better seal. O-rings - Replacing the O-Rings with the proper size O-Ring is important. Many aftermarket rings are off by a bit, and can cause you to run low compression. American sizes are slightly smaller. It's best to get the OEM stock or appropriate metric size O-Rings for proper rebuild results.
