Ok, so when I first road this bike, the thing just hauled all over the place and really pulled nice on the low end (much better than I expected after reading the reviews). I know this bike is not considered the best for low-mid range grunt, however, compared to my first rides, it seems to be getting worse. Is this just the bike breaking in and I'm now starting to see how the engine "really" performs or did I not break it in incorrectly? It still has the very fast top end and has a strong hit towards the upper end of the midrange. Is this normal? Even new I could see how a pipe or slip on would have helped on the low end, but it still was very impressive at this stage. Is a pipe/exhaust in order at this stage? Thanks!
