I modified my sons xr clutch lever. Take a look. The job took 30 minutes, drill, 1/8 bit, 5/16 bit (i think) let me know if You need me to explain further. Same principle as the MSR Raptor. picture 1
Hard to imagine why a bike geared to the little ones has such a solid pull and a loooong reach. I did the same mod a month ago when we got our '02 and it made a huge improvement. I'm still considering ordering up some KTM 50 lever assemblies since they are closer to the bars. Worst case would be ordering up a kit from E-rider which would require a different hose between the slave & master with a shorter length. (why yes I did investigate this in depth) ;)
