I loved the sound of the Jardine but found it too distracting so off it went. I was surprised by how much quicker the throttle response was in the under 6000rpm range where I normally ride. I suppose the bike may have been faster at high RPMs under full throttle but I couldn't really tell. I like being able to open up the throttle without worrying about alerting the cops or pissing off other motorists. It was fun while it lasted.
