i currently own and have just bought a gpx-4 pro. it has a rossi pixi black and a centax 3 shoe clutch. i have tuned it well and i have turned the little set screw anti-clockwise to make it change into 2nd quicker but it still wouldn't change. i took apart the clutch and loosened the little spring alot and yet again it still wont change. and yes i am sure i have a 2 speed in it lol.
 
hmmm,


Sounds like you're adjusting your centax to engage your 2speed? try the actual 2 speed assembly there should be some sort of engagment screw that you could adjust to make it shift. good luck

Could be to much endplay or the clutch nut How much endplay do you have
 
End play is a term associated with centax clutches (push type). It's the measurement of how much the clutch bell will move back and forth during engagement of the clutch.
