At first glance, Kawasaki didn't do me any favor in regards to adjusting preload on the rear spring. The manual says to have it adjusted by the dealer and they dont give you the tool to do it either.
(My Z400 came with the wrench)
Since this is new for me, is there a special tool anyone can recommend? Or are all wrenches the same? I haven't looked yet, but I recall access to the adjusting nuts looked real tight, is there some disassembly required? Any tips from the forum pros? I'm keeping the stock suspension at least until the warranty expires, I just may need to adjust it for my weight and riding style. (If needed)
