Now, Claire, with your analytical mind, I'm sure that you understand that if you never tried another cam, you didn't have anything to compare against....
Tons of exhaust duration for street applications, has been a band-aid for a non-existing problem, IMO. The extra exhaust duration does have a different sound, which is what most guys go after though. That's why the Thumpr cams have so much of a following.....tons of exhaust duration (over 14° difference) with a short LSA. All show, no go. Less gas mileage, stinky idle, etc.
