I'm going to install Goodridge Speed Bleeders on my 2004 Yz450f. These replace the regular brake bleeder nipple, with a unit that has a checkvalve so that you can bleed the brakes without somone else to assist you. My question is what size are the threads of the stock bleeder nipple?? Goodridge shows: 7 mm x 1.0 8mm x 1.25 10mm x 1.0 I'm guessing the Yamaha uses the 8mm x 1.25, but I'm not sure. Any help appreciated.
