would it be the m3 or m4? Oh yeah and by the way, my 2 speed isn't working and it never has but don't you udjust a spring or something???
you adjust the grub screw, there is one that holds the 2 speed in place and one that adjusts shift rpm's. clockwise it shifts at higher rpm's and counterclockwise it shifts at lower rpm's. be careful not to over tighten or over loosen the nut since it will crush the spring of the grub scew will fall out. do 1/2 turns at a time and try it out.
