Alright i have read a bunch of post about clutching and i really dont understand what i should be doing. I have a 1993 Indy 500 EFI that is currently stock. I believe that it has a gold spring with 10m wieghts in the primary and a red spring in the secondary. Now i have no idea what this means...so any help would be great. I want to eventually clutch it to shift higher and give me more punch out of the hole.
