My Ryker rally only has about 500+ miles on it. Since this is an oil thread, I’ll tell you what I did. Back in Dec when some had concern about low oil, clunks and other noises in the drive tran, I decided to change trans oil and the final drive fluid. The trans must have had the 5w-40 in it because it looked on the thin side, mind you, the owners manual gives a broad line for oil. From what I can remember, trans could use 5w-40 on the lighter side to 75w-140 on the heavier side. I used the heavier in the trans. I changed the final drive and it looked much heavier and good. Then replaced it with 75w-90. I would say minimal sluff? on the drain plug magnet on Final drive, and moderate sluff? On the trans drain plug. I feel better knowing that I have the right amount and viscosity of fluids in my Ryker. PS make sure to clean the drain plug magnets. My engine oil and filter will be changed about 600-800 miles. I know some will think this is a waste of time and money but, it’s my time and my money. :cheers: cueman
