can anyone suggest at what mileage the trans fluid should be drained and filled on my 04 sixxer?(were talking a bike that takes a heavy beating daily)also what type of fluid should i use and how do i do it?
I don't think your bike has tranny fluid. I am pretty sure that the tranny is lubricated by the same oil you have in the engine. This is one of the main reasons you cannot run conventional motor oils in your bike but rather you must use motorcycle oil.
