Hi All

I purchased a Zoraki HP-01 recently and it seems like a great gun. After reading a bit about it I see it has a pressure valve to vent air if anyone tries more than 3 pumps to prevent it going over our legal limit. Mine however seems to vent on the 3rd and I am wondering if I am losing out on power with this. It feels like it gets hard to pump on the 3rd time then i hear it hiss and the pump closes easier.

Has anyone tried altering the screw to cause less venting? I have seen a few guides online, has anyone tried doing this?

I guess my first step would be to find a chronograph and make sure but wondering how easy the actual process is if I do have to do it.

thanks!
