Just wondering how far 103 twin cam heads can be shaved and what kind of compression change can be expected? I brought a 2015 fatboy in Feb this year that only had a 1000's k's on it. I've put about the same on it since then. Considering upgrading the cam. I've noticed most of the upgrade/stage kits increase comp by changing the pistons and that most of these pistons have valve wells for valve clearance in them. I like the look of the fuelling reaper 525 cam and also want to port the heads and upgrade the pushrods. I believe they like comp between 9.7-10.5. And I believe a standard 103 is about 9.6. Is possible to bump the comp up within this range by shaving the heads? Just seems a shame to throw two hardly used pistons over my shoulder.
Where does your CR and CCP land with thinner head gasket options?
I'd be lying if I said I understood what ppl are talking about in regards to corrected compression and all that jazz. Would changing a head gasket really make any noticeable difference? I'm guessing maybe a combination of shaving and the gasket. I really have no idea of what sort of difference in compression to expect from shaving the heads or if this Is even viable option.
