Lower the Compression on Your 2023-24 KTM 300 SX/XC and Make an Easy 3 hp.

Lower the Compression on Your 2023-24 KTM 300 SX/XC and Make an Easy 3 hp. High compression heads may be the biggest scam in the world when it comes to newer bikes. The compression needs to be in the 180-190 psi range for the best power no matter what the elevation is. We made new head inserts and lowered the compression from 205 to 185 psi, and made almost 3 extra HP on top with no loss of bottom end.
