Well, as I have mentioned on other threads here, I am pretty new to dirt biking (and I am hooked). Anyways, I also have re-jetted my KDX 200...and wow, what a difference!! It's also SOOO much easier jetting a dirt bike compared to a street bike (ZX-9).
I ride a lot (well, lately anyways) at Rampart Range near Denver, CO. My buddies dad got a GPS unit....and combined with the maps you can buy for the area (the ones you carry, not the downloadable type) are priceless. For me anyways :laugh:
