Im currently using a 1990 xt600e to race at mablethorpe beach in the uk. Basically its a 1/4 mile oval, on sand. What are the best mods to make the old pig go better? Im currently using standard gearing and im thinking of dropping one tooth on the engine sprocket so that I can set off in 2nd gear as 1st is far too short, will that do it or will I need a larger rear sprocket as well? Also has anyone used a straight through exhaust? Im wanting to make it lighter as the lazer exhaust fitted weighs a ton! My thoughts are to make one that goes under the motor, basically to keep the weight lower down and to make it look a bit more dirt or flat track style! Any help will be greatly appreciated!
