My last oil change I did on my 2014 Look on Amazon for Red Line oil change packs. Mine included 5 qts. engine oil, 1 qt. of Red Line Shock proof transmission oil and 1 qt. of primary oil. You will need to order a extra quart of primary oil because the primary holds about 3-4 more ounces than a quart. I did notice that my bike does not clunk quite as hard on the initial first gear engagement when the engine is cold when using there primary oil.
