All Harley recommends is their Transmission and Primary Lubricant for Sportsters. Now, what weight it is or any additives for the clutch that may be in it is Harley's secret. Also, the "viscosity" rating for gear lube and engine oils are different and I'm not sure how they relate to each other. I've seen advertisements for a 75W90 lubricant for V-Twin transmissions but I'm not sure if that works for the Sportster since the transmission and the primary (which includes the clutch) are lubricated by the same lubricant.

I would think that you would want a lubricant that would have a "high pressure additive" or "anti-shear" additive in it. When you look on the container, you'll see an API code in a round circle. Most of todays oil only carry one rating for use in gasoline engines. Usually it's as "SH" or "SJ". You need an oil that is rated for use in diesel engines to get the additives that I've just talked about. The rating on the container will read something like "SH/CG4", the CG4 rating being for diesel engine use.

Unless you are in an area where the availability of oils is limited, I'd opt for the H-D oil or one of the oils packaged by someone like "Motor Factory" or "Revco". You may find a recommendation by going to some of the oil companies like Shell, Mobil, or Sunoco.

Good Luck

What weight of oil is standard for a 02 Softail fxst standard


Hi, Joe proper oil weight is based on the average temperatures you expect to ride in between scheduled maintenance services the higher the temperature the heavier the oil and the cooler the temperature the lighter but to answer your question 20 w 50 is the standard weight for most conditions, using a Synthetic blended oil (HIGHLY RECOMMENDED) will be added protection for those unpredictable weather conditions. If you are still unsure refer to your owners manual and give your local Harley service department a call for their recommendation for this scenario you will need your service/owners manual if you can not find the first and best tool you ever bought for your Harley, despair not, for a mere zero $ you can download another one.

Transmission oil viscosity for fxdl harley davidson


This is a good question. Normally, the bike calls for 80/90 weight oil but the newer HD performance engines, transmissions and primaries use a good 40 weight in all three areas. I know of quite a few people that use 40W and they all say the bikes run cooler, shift easier, better performance and better mileage.

Can i use a sub. primaryfluid for my 1976 iron head sportster


Yes, you can use most any petroleum based oil that you want. I'd avoid the use of synthetic oil on that bike as it may cause the clutch to slip. The clutch discs in those early bikes are not very heavy and slip easily. A lot of guys just use straight 30 weight petroleum based engine oil.

What is the recommended transmission oil weight spec for 2010 wideglide


Your 2010 WideGlide came from the factory with H-D Syn3 20W50 engine oil in the transmission. That's why it's called Syn3, it's synthetic and goes in all three places, engine , primary, and transmission.

When cold the bike is hard to start, when hot , no problem. When i installed cams,I also went from 20x50 oil to 20x60. I read in the service manual that this could be causing the problem


There is no need to go to a heavier oil, Harley 20/50 is more than sufficient for these bikes. The only time i would recommend changing the kind of oil is to synthetic. be it ams oil or syn3 only upon that your get caught in traffic a lot or are a "cam rider" as they call it. personally i am a cam rider, i am always on the power band on my 2006 flstfi with 103" engine and Harley 257 cams. only in early evo and shovel head engines do you change the weight of the oil due to temperature changes hotter out use 60 weight colder use 50. just for easy starts and no leaks.

What weight oil goes in transmission on a 1999 harley davidson road king with 88 cubic inch motor


Mostly all motorcycles use the same oil in their Engins and transmission, you do not needs to put a seperate oil into the transmission, as the engin and transmission uses the same oil, you will also see that there is nowhere that you can top up the transmission oil, most motorcycles use 20W50 oils, but it can also depend on what country you are from

I would like to know what weight oil i need to put in my 2002 sporsters crankcase


A Harley Sportster, and their Big Twins for that matter, do not have oil in the crankcase. They are what we call "dry sump" engines in the fact that they carry their oil in a seperate remote oil tank.

On your Sportster, you can use Harley's Syn3 20W50 oil in the oil tank. There are other manufactures that make fine oils suitable for your engine but you'll have to check their websites for their recommendations. Amsoil, Royal Purple, Mobil V-Twin are a few.

On the transmission and primary, I'd use H-D semi-synthetic primary and transmission lubricant. There may be other brands that are available as well.

Good Luck

Just need to know the specs for fluids (oil & gear) on my 02' Dyna FXD


On the '02 bikes, the engine, primary, and transmission came with Harley-Davidson SYN3 synthetic oil in all three areas. Three quarts of engine oil, 32-36 ounces in the primary, and 20-24 ounces in the transmission.

The SYN3 oil is a synthetic 20-50 weight oil with a "C" rating on it. Check the API code. It will say something like SJ-CG. The "Cx" is what you're looking for as this tells you that it has the high pressure additives in the oil for use in diesel engines. Harley has always recommended using "C" rated oils in their engines.

Oil in airfilter 883 sportser


Everyone has oil in their airfilters. Harleys are engineered to vent the crankcase thru the carberator. Some oil will get into the filter. There is nothing wrong and thats not whats causing your bike to run ruff unless u have a paper filter thats clogged with oil, in which case I would recommend replacing it with an after market filter that is designed to be oiled like from K & N which are washable and reusable .
