I'm a 17 year old kid from norway. I've been riding motocross for five year's now and just bought me a Kawasaki KLX 300 for the streets, (still riding mx, on my YZ 250 '2000) but it isn't fast enough..! Do you guy's have eny tech tips or tuning tips for a KLX 300 or 650?? The bike is stock. And do the KX 250 plastic fit the KLX 300?
