i see here several subject are mixed together: hydraulic clutch, clutch lever, too soft clutch, etc.
in my opinion hydraulic clutch is waste of many on this bike as the clutch is already very easy to operate. (one of the purposes of hydraulic clutch is to make clutch softer). no need to fix something that already works so well... unless one is doing is just for fun of it.
however, adding heavy duty clutch spring would give the bike more power, especially on lower gears. i made the conversion in crf 250L and it made a big difference. i ordered some heavy duty EBC couch springs for gs, but did yet have yet the chance to install them.
I did not yet fit Puig Clutch lever, as I am away from the country, but I am sure it should fit perfectly, as for some reason the Chinese are unable to make the exact replica of the oem lever.
as you love riding, you need to love you bike
