OP, what’s the static compression of your 124” kit? That 590 cam is gonna want around 12:1 static…it’s a real hot rod of a cam too…lot more cam than the 540.
I know it's a little late response sorry. I appreciate all the feedback. The compression is 11:1. I ended up keeping the 475 cam for now. I'm actually still working on the bike but the engine is pretty much done. I'm waiting on the Man-O War Compensator. I did the Screamin eagle high rate springs and Recluse hydraulic slave cylinder. I really only changed the slave because I got rid of the transmission side cover and had the real side cover powder coated. Also waiting for the transmission top cover. Made my own crank case breather and having it powdered wrinkle with the rest of the parts I swapped.

I think you should cancel the compensator and get a compensator ramp.

Why do you recommend that? I'm all ears on other people's recommendations but I don't know why the ramp is a better option.

Why? It looks to be an M8 build.

I was wondering the same thing? I actually have had the cam plate in already for maybe 6000 miles. I took it all out while I was doing the 124 build and everything looks great. The only thing I noticed and has nothing to do with that was trany fluid in my primary. I'm going to try the tapered push rod for that. Is there something I should be looking for by having the S&S cam plate in there? If it's really going to be a problem then there's going to be a lot of angry people. I'm sure I'm not the only one who did this mod.

The moonshine HD guy are about as good on the theory as Kevin Baxter or Don Pederson.. In that case listen to their experience..

Watch the whole video if you want, much of it is BS, we want your dollars stuff but what the say here is the main thing.
