Have 10000 miles on my bike does the shaft drive oil need to be changed or what?
Final drive assemblies on motorcycles generally cost over $1000. They tend to show signs of dirt after only 5000 miles. Having driven shaft drive motor cycles for over 30 years I usually change my 85/90 Hypoid gear oil at every second engine oil change. It is never very dirty but if taken into the sun light will show some fine metal chips (nothing to worry about). I highly recommend using synthetic Hypoid gear oil. It will cause less friction and the final drive will run at a much cooler temperature. One quart of Hypoid gear oil will change the rear end oil 3 or 4 times so it is good, cheap preventive maintenance. Simply take off the large fill cap, place a pan under the small drain bolt at the bottom of the pan,remove the drain bolt, drain the oil, put the drain bolt back in, and fill the final drive to the bottom of the larger fill hole (usually a quarter to half cup of oil), then replace the large cap being careful to only snug it tight enough to seal in the oil. If you over tighten it, it is designed to break! Be sure to check the owners manual on the exact amount of oil to use. Honda has changed the fill technique for some of the newer models. With a higher fill hole on some newer models you may be over filling the final drive, so you may have to measure the amount. Too much oil will cause waste and may cause over flow out the top vent. Happy Trails.
