Now Iâ€™m only new to bikes so I donâ€™t know if this is normal or not. I have a 2001 Cagiva Mito 125 (and a 1993 Mito unregistered and 4sale) When I try to take off fast at the lights the bike sort of bogs down, it goes then sort of hesitates and chugs, itâ€™s not until I get right up in the reves that it finally takes off. Am I giving it to much throttle to soon or something? I took my other bike (1993 model) out for a run for the first time last night the engine sounds real beafy compared to my 2001 model, it must be the carbon exhaust giving it that nice note, when you hit power-band it really packs a punch, I wish my other bike went like this. I think I need to do some work to get my bike up to scratch. Does an after market muffler make much difference to power? Or just sound nice? I really noticed the difference on the early model bike without the steering dampener, although the 93 model bike goes harder the 2001 model is a nicer bike to ride.
