Before you guys start spending hundreds of $ on pipes and performance parts, have you done, or confirmed that the same free hopups can be done as the KLX300 ? Has anyone taken off their 1" crankcase vent and found a plug with a 1/8" hole in it ? These are where you will get the biggest gains and they are free ! After that you can spend another $800-1000 on a pumper carb & head pipe if you have more money than you know what to do with.
