TM2 OR V2 SPUR GEAR DIFFERENCE
 

Hi, i've just got a TM2 with upgrades, how do i tell whether the spur gear is tm2 or v2 ?

tm2 v1 and v2 kits use tm2 slipper. I think v3 tm2 uses tm4 slipper, but there are very few tm2 v3's around.
Most people use tm4 slipper because it is better; kit tm2 slipper tends to be either "on" or "off" rather than limited slip. The tm4 slipper is better. The RW conversion uses tm4 slipper.
You can tell which you have I think because the tm2 slipper uses a circular adjustment nut, whereas tm4 slipper uses a hex nut.
