Some of the bikes had the issue not all, mine didnt have the vapor lock issue. I'd say do it anyway as a just in case. you will be happy all getup when you get your "Dream Weaver" (LoL) mods :thumbsup:
once mine is installed, cant seem to want to give up my bike for a day let a lone a week :lol8: I will be getting it Dynoed and report the findings. there is talk from a Heist rider in AZ that his bike is hitting 117mph after the port polish and milling. Until I see real world proof :deal: I'll live to dream :icon10:
