Alright so I have my cocker that I just built. Its timed and shooting well enough except I cant really get it past 240 fps. I have the reg sweet spotted as best as i can without a barrel kit (hopefully Santa will bring me one). Anyways I have a blue main green valve and I cant get the gun to go past 240 fps. I even screwed the ivg in so far that the gun wouldn't reliably recock. Any ideas? Should I try a red main?

Ideally I’d try swapping out to a blue valve spring and resweet-spot your inline regulator.
You could try swapping in a red main spring, but you would need to raise your LPR to compensate for the increased spring strength to get it to recock reliably and your marker probably wouldn’t feel very smooth.
What kind of body is it?
I’ve got quite a few autocockers and I don’t think any of them have the IVG more than three threads in to hit 285 FPS (+/-).

Your reg will be sweet spotted when you're shooting 280fps with whatever springs you have.

There's a slim chance your backblock is catching the hammer right as it hits the valve... But only if you're timed very, very tight. Loosen your timing a hair if, and only if, you can't fix it with springs, or if you're noticing the gun "bobbles" a stack of three balls in your feedneck.

I would say that you should bore match before you try to fine tune it. If you can, borrow a sized barrel and see what gains you get from it. Other than that, I would agree with flyweightnate regarding too tight timing.
