| I know everybody always says, ooh don't do this or don't do that, you'll loose midrange power. I don't really buy that. It seems to me that if get a bike tuned properly, that is not just bolt stuff on, but get it sorted, you're much more likely to gain power everywhere. If you don't you need a different tuner!
Having said that, I am a firm believer to get the best out of what you have. Often, that is enough of a difference. And lastly, remember the best money spent on Dukes is to get the suspension setup properly by the likes of K-Tech, etc. |
