That means run it at like 1/2 throttle or 3/4, not full all the time. If you do, you'll know when it's really frickin loud. If you do that your top end isn't goin to last as long but don't lug it either. CR's don't like low end unless you get some stuff for them, and lugging them still isn't a good idea, they just lug a little less and have more low end grunt. Go to your Honda dealer and see if they have a Fatty pipe. If they don't, order one. They're about $150 I think, I haven't checked in a while. Also, if you don't get a bike that has one, you'll need a spark arrested muffler. I don't know if they require one where you ride but if I rode without one, I'd be in serious trouble. FMF Turbine Core II is what I've got on mine, $140. So if you get everything, it'll be about $300 just for extras, maybe a little more.
