New to Harleys here. I was wondering, what are the cam specs on my stock 2001 XL1200c Sportster? You guys refer to cams by name, or part number or sometimes lift; on musclecar sites people talk about them by duration, lift and lobe separation angle as well as lift. Is it true Harleys run super tight LSAs because the carb is practically on top of the intake port? How would a Harley run with a divided long runner intake and a wide LSA? Wide LSAs are supposed to give a better idle as well as allow the engine to be still pulling at the redline at the price of possibly reduced peak horsepower; that is, in a conventional pushrod V8. I was shocked to see the Harley is a hemi head design; didn't know until I saw one at my mechanic. How many aftermarket heads are made for my 1200?
