Is it safe to take 4 coils from tappet spring?

worst thing that could happen is either the spring or the tappet plate breaks

and that's not the worse thing in the world to replace.

Ok one modified tappet plate I removed a small amount at the top so it picks up a bit later and removed some from the bottom so it goes back faster should I take a bit more from the bottom or do you think that's enough

Give it a go and see.

You dont want to go higher than the axle of the sector else it'll start reducing the stroke (with inevitable feeding issues)

So I've finally fixed all my issues I short stroked by one tooth which to be fair I needed as I was over for my cqb sight and use the custom tappet plate and spring I now get perfect 294 to 297 on semi and 290 to 295 on full auto which is close enough I use 3 round burst anyway and that stays at around the semi fps level.

Who would have thought a simple motor upgrade would be this much stress especially as its pretty much the same rpm as my stock ifrit motor
