i new to all this and i was just wondering and it has prob been asked and answered before but does an air filter, better reeds and a better exthaust make a noticable change in performance
YES, a good air filter and also a good fuel filter will both let the engine breath how us humans do and the good fuel filter will keep out any pieces of bad stuff that will stop the engine just like our heart. if you replace both the reeds with [fibreglass reeds] and the pipe with say a fatboy your engine will come to life just like we train to become fitter.
