I have a 99 flstf with compression, cam, exhaust and high flow air cleaner, but the carb is a rejetted stocker. Anyone have any REAL ideas as to any HP/TQ gains the HSR 42 kit would gain?

Also the ignition is stock, so the same question goes for the Crane hi4 module and single fire coil, worth it? or save the cash.

Thanks!

CV is fine for 80". You don't need a bigger carb till you get more inches. Save your money and get an ignition with a higher rev limiter. There is no real benefit to a single fire ignition except with the right cam it sounds cool idling.
