Does any one know if the 3 port piston and sleeve fit in the Go gx2 5rho? Have one of the older ones with the 2 needle setting that I'm going to break in. Going to order a rod off amain to replace after break in and saw the 3port p/s for $29 I believe. For $29 that would be a good back up or good for practice. Not racing as much but can't pass up a deal when I see one.
