Took the bike out today and the weirdest thing was happening. As I accelerate in any gear from 5000-7500 rpm, the bike seems like it has the hiccups and won't really accelerate. I have to turn the throttle a bit more aggressive and get it to about 7700 rpms and then its fine. theres a little popping noise everytime I accelerate throught that rpm range.
Anyone ever experienced this before?
Any ideas what the problem could be?
