Nice input Kev, thats a reasonable low cost mod. I also try in other bikes to raise a bit the oil level, just a bit no more than 25-30 cc wich is aprox 20mm level. Thats provide an extra stiff force on the last travel of the forks. The suspension become stiff when is almost topped down. It has no efect on the fist 2/3 of the travel. But you have to be carefull do not overfil the legs or you'll blow out your seals soon.

Just an input...nice mod KEV
