My OEM quick shifter is absolute garbage. Using it creates some serious suspension issues from front to back, and I'm assuming it is because it is so slow. I can shift way faster using the normal preload shifter and throttle off/on without upsetting the bikes suspension. How do I fix this?
Yes my front suspension is set hard (not max), my rear is also set hard, but my preload is .... I don't know... I'm guessing hard as well because the bike barely sags when I sit on it. I'm a heavy dude. 210lbs.
more information is required, whats happening when you shift with the QS?? sounds more like your suspension is setup incorrectly than anything else
