Im new to racing banshees and i have a 485 cheetah kit with power valves, 35mm carb, dynatek ignition with stage iv pipes and heads and domes. what size domes should i use if i want to run race gas and should i get a timing plate? What should i set the timing plate to if so? its kinda important for me because im going to race a raptor in a few weeks so please help me out. Also what type of oil should i mix with 110 race fuel and the ratio?
