This video shows the complete process to replace your piston in a fuel injected (TPI) two stroke by KTM, Husqvarna or GasGas. The steps will vary slightly depending on the model and engine size, but the overall process will be the same. The bike in this video is a 2020 KTM 250 XC TPI.

This top end rebuild was at 73 hours, and my piston and cylinder were in awful shape. I do not know if this was a result of something I did wrong, or if the bike was simply not getting enough oil. Regardless, I had to send the cylinder out to Millennium Technologies for replating. The bike is running strong after the top end rebuild.
