I just took a time observing at the throttle cables and found that they actually look fine, I am having and errant idle, which I usually tune it around 1.5k using the idle adjuster, I think thats here where somehow a dragging fact interacts with throttle play, making it sound out of armony, until I drop it from 2k to 1.5k using the mentioned knob, it gets more stable as the bike warms, but overall my system sounds a **** sometimes at low revs and I have to constantly adjusting the idle adjuster knob, any idea? It sound ugly from 2k to 4k, but sounds very cool above 5k, just like a rocket jeje.
