Yeah, I have an inline filter, shame on me for not noticing how EMPTY it was and wondering why my bike wouldnt run... However, I will say that the bike runs WAY better now, stronger response throughout the throttle range (esp top end). When my GF showed up with a gas can, It started right up and blew a HUGE cloud of foul smelling blue smoke for about two minutes. Im thinking some crap got flushed out, the gas was new, not sitting in the can.
