One of the best mods we have found for the KTM 85 platform, whether it's an 85 or a 105 or 112 supermini, is a bored and modified carburetor. This mod is also effective on all other brands - from kx85 to yz85 and rm85, as well as gas gas 85 and husky 85. Check out our video of the mod process, as well as the dyno charts of what results we got. To be fair, this was all stock vs bored and jetted right, a stock carb jetted a little differently would have been closer but we typically see nice gains in the 1hp range.
The ultimate gear head, I just want to make everything fast.
