I think that we could still use the GSXR cartridges (at least ones that aren't melted  ). In any case, we aren't going to get what we want without some creative modding.
Makes the F3 cartridges actually look like an easier option! |
Precisely! The stock Ninja 250 springs are very light already, and we need like a .75-.8Kg spring for racing. So, I was thinking that the Ninja springs cut to length might not be too much spring rate.
Don't know if Zoran changes the springs for the cartridge install, but have you measured the springs on the GSXR600 cartridges you have, and are they the same diameter as the ones I have? Let me know what diameter the spring and cartridge is on both the GSXR600 and CBR600F3 cartridges that you have. Good to hear that the caps will thread the adjusters from the GSXR600 to the CBR600F3 caps! We always have the option of drilling and threading the EX250 caps, too, with the o-rings already there.
