Hello everyone. I'm coming here hoping you guys can assist me with some info. My dad has a 2007 Road King. To date I've installed a set of S&S 585 cams, the S&S "Sidewinder" 2-into-1 pipe (can you tell he grew up using S&S because they were the shizz back in 1982?!), a FuelPak legacy tuner, and made a spacer for his air cleaner cover to allow a little more airflow into it.
I've got a bit of engine-building experience, with both my carbureted Sportster and my '11 Street Glide 103, but those were generic bikes and I didn't mind modifying the factory parts doing stuff like milling/porting/polishing/etc. Dad tells me he doesn't mind swapping parts, but wants to be able to "revert to stock" if he ever decides he wants to sell it. He also tells me "I want it to run as good as your 103, it's a 110 and it should be able to outrun you!". Haha!
But seriously...within the constraints of not doing any headwork, keeping the parts I've already used, and being able to keep the original CVO air cleaner cover on it, what's my best course of action for hitting 100 rear-wheel horsepower?
Would a 58mm throttle body and set of 5.7g/s injectors be likely to get me there, or at least close?
Will the factory valve springs support a 1.675:1 set of roller rockers, considering he's already got the 585 cams?
Will the duration of the 585 S&S cams support a 10.5:1 compression, should I go to a longer-duration cam if I use those pistons, or should I just go with thinner gaskets to give a small bump in compression and keep the 585?
