I got a knockoff greddy rs in the mail today, (I paid for a S, so thats cool I guess) anyway, I have read somwhere on here that you are supposed to remove one of the springs inside, I'm just not sure which one.

 

put it on and see how it works before anything

 

Alright i'll do that, I dont know if its normal but when I press the plunger with my thumbs, I have to press VERY hard and it only moves into the body about 2 centimeters, is this normal or does it just need vaccum to open up all the way?

 

With my Greddy Type-S knock off I did'nt have to remove any springs. I just left it as is and it works fine.

 

if not then remove the smaller spring
