G'day and hope you can shed some light on the small dilema I have with the speedo on the 56.It will only go up to 25 and no further no matter how fast I go.I have removed the speedo and cable,tested the speedo with my cordless drill attached and it went from 0 to 120 and everywhere inbetween smoothly when I changed the drill rpm's,so I'm guessing the unit is fine.Next I tested the speedo cable in its installed position and it was easy to turn so I'm thinking the problem is in the drive in the gearbox,of which I have no idea how to access,inspect or test.Any enlightenment appreciated or perhaps something overlooked?The box is stock unmodified 4 speed.Since joining the forum I have been doing some homework on oil recommendations and there seems to be many differing opinions so I would like some advice as to what other forum members think about correct or better oils for engine,primary and 4 speed in my 56 which is stock,unmodified(except s&s carb)Most oils available here in Australia or online.Your thoughts and advice on this contentious issue will be appreciated,PB
