Welcome. There's a lot of info on here about the throttle thing, but don't get swept up in too much crap. The first step is ensuring your TPS is set correctly, then you can look at fuelling.I just bought a 2016 GSXS 1000FA!! First sport bike since 92 which was a ZX11. I love it so far. I do hate the jerky attitude it has at low speeds. Anyway, looking forward to learning a little here.
I would set the sag and ride it 500-1000 miles with the stock compression and dampening settings for the front and rear and see how you like it, then tweak it from there.I have a GSXS 1000FA, I weigh about 290 without any gear. Any recommendations for suspension changes\settings?
