A few things still on my "to do" list for this bike is to order some of the custom carbon fiber V2 reed's made for a '87 zilla from Tuders Performance and get a new clutch with billet clutch basket. Then I wanna shave some weight off of it so I'm gonna replace the factory front spindles with a aluminum set from a z400. They are a direct fit to the quadracer if u run upper ball joints on the upper and lower A-arms. You have to run the z400 hubs with them after that though which changes the lug pattern. I also read that yfz450 dual piston front brake calipers are a direct replacement for the z400 calipers so if I am switching hubs and spindles, I might as well switch calipers too. After I do that I wanna find a aluminum rear brake hub since the factory one is steel.
