Retro Valve Part Questions

[Fugifilm]

I have afew questions about the retro valve...
1.Would the RT/retro on/off ***. fit in the Classic Valve? and if so, would it improve the speed of my trigger pull?
2.Are there any more crutial parts that will fit in the Classic valve that would improve trigger speed?

THX for your help

The RT on/off will fit and function in the Classic Valve, but you have to spend time tweaking the on/off pin length and it's very easy to short stroke.

The best thing to do is get an Intelliframe and shoot the gun a whole bunch. Also, if you run HPA all the time, swap out the teflon o-rings for urethane o-rings from an RT parts kit. It reduces the friction on the on/off pin, reducing the pull force a bit.
