I need 2 do oil changes on my 97 Dyna Low Rider. 1. Type and amount of oil for engine? 2. Type and amount of oil for clutch / transmission? Thanking you. Spy.

Your engine holds three quarts of oil, 20W50 petroleum or synthetic.

Your Primary holds about a quart of oil. Stand the bike straight up and fill up to the lower edge of the outer clutch basket through the derby cover access. Do not overfill or the clutch will drag. H-D primary and transmission lubricant.

Your Transmission holds 20-24 ounces of the same H-D primary and transmission lubricant. Stand the bike up straight, remove the plug from the chrome end on the right side of the transmission that takes a large hex key to remove. Level should be between the lines on the dipstick.

As for what brand of lubricant, there are many of them on the market that are sufficient to do the job. I stick with H-D lubricant for the primary and transmission. I like H-D, Mobil V-Twin, or Amsoil for the engine. Whatever brand you choose, check their website for suitability and their recommendations.

Good Luck
Steve
