103" power upgrade
Hi all, I am currently riding a 2016 fatbob, with a stage 1 kit and a set of SE 211 cams. I have been looking to do another power upgrade and was thinking along the line of 110" barrels and high comp pistons. Have any of you's done this or something similar? How'd it go? Will the heads/valves and rest of the engine handle it? Etc. cheers in advance

If you now have a set of 211 cams, you're already up to a "Stage 2", if that's what you choose to call it. If you want to go 110", you'll have to reconfigure almost everything so it all gets along together. Heads, cams, cylinder bore, intake, exhaust, etc, etc, etc. I suggest you do some serious reading on here before deciding to take the plunge.

If your bike is still under warranty then you may wish to start at the dealer and look at the various 110 kit packages. One of the nice things that Harley does is give you a projected view of how much performance gain you can expect.
