The Crocket one is available, made here in Australia, the whole assembly is new, you don't use anything off the original setup except the cable connector and the return spring and pin....way better set up, way lighter clutch pull and the clutch lever has a modern feel to it. The push lever starts out life as a NOS TX650 one, has the lever cut off, a new 20mm longer one is tig welded on then it is re-zinced. The TX push lever is a 4 helix design, it's also metal.... not like the shit plastic 3 helix on the std DT1/YZA/B style that are always cracked even when you buy a NOS one for a hundred or so dollars.. A new female helix is CNC'd out of a special self lubricating plastic and bolts into the housing. I have 4 left at the moment if you want one. You can PM me or ring 0412 747 729, cheers John.
