Hi everyone. I've got an 03' KTM 125sx. Factory engine with an FMF Fatty Pipe and Shorty Silencer. Gearing is set at 13 front 48 rear giving me a ratio of 3.69. I live in Northern Maine and there's hundreds of miles of railroad beds to ride (obviously no tracks lol) which is why I've got it set with taller gears. I understand when you add or take away from one end you get the reverse effect on the other but my bike is just about nutless on the bottom end. Has anyone tried or had any luck using flywheel weights. After some research it sounds like a 6-8oz weight is what I'm after but would like to hear from other riders. Thanks for any advice.
