I have a 2010 badmax that my son races. He is moving to JR2 this year and I have to add 60 more pounds of lead which now means I will have more lead weight than driver weight. While installing his motor I noticed he could get his elbow right between the seat and guard/shield with ease. Its a pretty large gap. The question is not should I fill the gap but how. Extend the shield and just add the weight and rescale or move the seat over and foward closer to steering support and engine. The gap between steering support is rather large also, about 4 inches. Nose is 47%, Left is 54%, and Cross is 56.3% at a weight of 263.
