Hey guys, I am a new yz400f owner - I recently moved up from a ttr125.. big change. I am a novice who mostly rides in tight woods/trails and this big bike is manhandling me I wanted to get a flywheel weight to help with the chugability and stalling, but it seems I can only find them for the 450s. Will a 450 weight work on a 400? I figured a 426 will work, but I assume the 450 was different. Do I have any other options? Maybe just a stock wr flywheel? thanks for any advice!
