Just to share with you guys ... wow today i was amazed with my Go 5 port (go efra 2047 pipe). Tomorro i have a big national level event in my country (Chile) and today was the open practice day ... and as the track its very technical and does not have any loooong straight i tested a 6.5mm insert on the carb and WOW ... went from 8.30 minutes to 11.10 minutes of runtime ... very strong, with good low and high end power (compared to other engines mainly RB WS7III, mine was as good as the rest in power).

Hope to make it good tomorrow ... cya !!
