If you are using steel sprockets you can save a bunch of weight by going to aluminum. If you have access to water jetting or even the IFI parts are better than hanging on the the kits steel sprockets. If you are using the 8" or 6" wheel chair wheels. You can improve traction with rough top or diamond top belting. Use a lathe to make the rubber part flat and use good glue and screw to hold the belting on. Last year we designed hat like things to go on the kit transmissions that held aluminum sprockets cut the weight of 4 wheel drive by 1/4 or more. Also if you are using the skyway's use a 1/4" thick donut to keep the chain out of the wheels. The other thing you can do at competition is have the gears in the kit transmission lightened by the machine shop or trailer. If you are doing this in a fix-it window don't plan so big as to go over the allocated time.
