do you mean combo as in what cam and stuff I’m running? I do know that peak torque is lower, I don’t think it’s 2500 low though. What if I retard the initial and use vacuum advance instead?
Or do I want more timing initially and limit the mechanical? I’m ideally trying to maximize mpg at cruise, but obviously a properly timed engine is the most efficient it can get.
When I’m getting on it, I shift at or just below 5k. Stock springs, so going over 5k isn’t exactly ideal for them. I can feel at around 4000-4500 the torque starts to drop off. Probably expected given the 650, dual plane, and torque focused cam.
