Hey guys, I have a marui-clone AK47 (upgraded with tightbored,hopup unit, new rubber hopup nub and a high-speed motor).

Originally this gun was shooting aprox 390-405 FPS with the stock motor and spring and a simple tightbore.

Recently I purchased a "X High Tech High Speed Custom Motor for AK" and slapped it into my gun. The ROF is WAYYY too high, my electric drum will feed into it, but my high-caps cant keep up with the ROF (about half the time the gun fires it's not actually shooting a BB). Now I rechecked my velocity recently and it's now around 300-315 FPS, a substantial drop....

I'm assuming this is cause by the motor not pulling the stock spring back enough, in order to spit out more rounds per sec?

I'm aiming to have the gun fire around 400fps (the limit on most outdoor fields). What would I have to do to get to that point?

I realize that I will lose some ROF and that is PERFECTLY fine with me (as my mags don't load right anyways since it's too high). Should I just swap out this new motor for a "slower" one? (If so, any suggestions?)

What would you guys do in my situation?

THANKS !
