Thunder Chicken = You guys are to loud! Why would you guys want all that power? The XR650R has more then enough power. Be real good or we will lose our riding area! What a bunch of bull! Just because you can't ride at a level that needs more power, or you don't like to push the limits doesn't mean everyone has to live by your humble opinion. California...do I hear a challenge? Hey Bruce, quit stirring the pot. SecretThunderAtlasChicken is just messin with Hill5150. Plus he is correct about losing riding areas because of noisy bikes, it is the number one reason and always will be. Those that do not recognize that are going to learn the hard way. There are only a handful of guys that are going to be able to manage the wide open power range of such a loud pipe. None of which would be asking questions about it on this forum. His advice is valid and probably saved that dude a few bucks. However, &%$#@! do I know.
