LCW Posted July 25, 2013 Report Share Posted July 25, 2013 I would say ditch those stock carbs and snag up some 35mm PWKS. That's the first thing I do when someone brings a bike to me, whether it is stock porting or not. That serval will love more air. Quote Link to comment Share on other sites More sharing options...
