Just had the bike mapped for Akropovics and big disappointment. The bike is now far harder to ride off road due to very very glitchy throttle and has developed vibration above 4000rpm! With the baffles out the engine runs slightly smoother but way to loud. My dealer reckons we could remap back to the original and then try the cans ? In hindsight the bike was near perfect before both on and off road. Anyone got any ideas apart from trying to sell the cans?
