Super 8 / higher speed?
« on: May 11, 2017, 05:15:11 AM »
so I just got my super 8 50x 2016 derestricted (main jet, smooth boss, manifold washer removed) and I can only hit 35 on a flat. Am I missing something here? the mechanic said he was surprised it wasn't hitting 40. Any recommendations for air filters and exhaust?
