Stock oil filter installed: 3.17 quarts if no filter change - 3.3 quarts if filter changed

DO NOT OVERFILL! FYi - there's a site glass on the left side of the bike, under the left riders peg. Make sure the bike is level, oil is warm and bike is off - do not let the oil get over the upper mark... just under the upper mark is good, a little closer to middle is better.

For the final drive oil you can use any 80/90 Hypoid gear oil. If you choose a synthetic Hypoid gear oil your rear end will run cooler. One quart of oil is enough for 4 or 5 rear end oil changes. Because the rear ends are so expensive (around $1000), I change my rear end oil every other engine oil change.

This can happen if you used the wrong oil. Is the clutch cable or hydraulic operation. If cable then it may be dry or adjusted too much (needs a little free play at the lever. Not sure of your knowledge so starting with the basics. How many Kms has it done.

3.3 quarts/change.

Oil drain plug is located near the bottom of the engine, left side toward the front. The oil filter element is located on the right side of the engine under the cover toward the front. Changing the oil filter usually requires removal of the front exhaust pipe. There is an aftermarket filter relocation kit that replaces the filter element with a spin on filter that mounts on the front of the bike.

Imformation on fork oil will be found in workshop manual ,or ask dealer mechanic.

sounds major. Clanking and low on oil sounds like a broken piston ring. Suggest dealer check with compression tester rear cylinder. Replace v star with Harley if necessary.

80/90 wt Hypoid gear oil is used in Transfer cases and final drives
