I think the later models are designed to use the same type of oil in both the engine and the prmary/transmission. But, I have never agreed with this. I use H-D Syn 3 20W50 oil in the engine but I prefer to run either Harley's primary and transmission lube or one of the other manufacturers lubricants in the transmission. If you use another manufacturer's lubricant, go to their website and check for compatibility for use in your Sportster.

Good Luck

Harley davidson xr1200, hydraulic lifter stuck

  • Harley equipped the 1200 Sportster line with an air-cooled 1200 cc four-stroke V-twin engine. The V-twin engine had two cylinders set at a 45-degree angle to one another. This engine used electronic fuel injection in an overhead valve configuration with two valves per cylinder and four valves total. It had a bore measurement of 3.5 inches and a stroke measuring 3.81 inches. It had a 9.7-to-1 compression ratio.
    The 1999 Sportster Custom's engine produces 58 horsepower at 5,200 rpm and 72 pound-feet of torque at 3,200 rpm. A dry sump oil system keeps the engine lubricated and the Sportster Custom relies on the air flow during riding to cool the engine. Riders can start the 1200 C with an electric starter; a CDI, or digital capacitor discharge ignition controls the firing in each cylinder.
  • The 1999 Sportster Custom transferred power to the rear wheel via a belt drive. Riders could shift through the gears of the Sportster's five-speed manual transmission by using the hydraulic clutch.

I have a 2005 Sportster 883, Always used shop to change oil & xmission fluid. Any problem using a standard 20w50 oil and 80w90 xmission fluid and do the work myself?

Hi Ron, I have no trouble with you doing your own oil changes but why would you want to use someone elses oil that was not designed for your Sportster to save a few pennies? If you needed a blood transfusion would you want it from a family member or some stranger? For more information about your question please visit the websites below. Good luck and have nice day.

Just need to know where the drain plug is on 2003 1200 sportster-friend lost her manual

For the oil? On the oil tank you will see tubes coming off the bottom of the tank, there is two one to the motor and one will drop almost straight down. follow the tube and you will see the plug. most times it will sit right behind the tranny on the rh side of the bike. don't worry about the motor holds little oil and the tranny is separate and holds its own oil.
If you need more help please let me know

Need information on the changing of engine, primary and transmission oils on 2006 883L sportster

Your looking at 2.8qts for the engine add another 1/2 quart or so for the filter. Always put a little oil in and then add till full. Use the amounts identified as a guide to how much oil to have on hand. You primary may use 22 - 28 ounces, and your tranny a little less than a quart. so have at least 5 quarts available for a complete fluid change (and filter) and you should be good to go! Hope this helps.

1984 F150 302 Had oil pan gasket and both valve cover gaskets

you have several points to check!
the dip stick tube has a "O" ring seal at the bottom where it fits to tranny.
a reverse switch on tranny & the shifters selector shaft has a seal that may be leaking !
there are the cooler pipes from cooler to tranny [in & out] plus pump seal to the torque converter [leaks out between engine & tranny bellhousing] & then there are the drive shaft or shafts seals
so wipe it all clean & park it in a diffrent clean spot!
some will only leak when its runnung due to tranny,s internal pressure!

Damon, on the bottom the drain hose has a plug. Remove the plug to drain ENGINE oil. When done draining (takes a long time as it drains slowly), put the plug back in and add oil to the oil tank on right side of the bike (don't forget to change the oil filter too). Transmission/chaincase/clutch oil is drained by removing the plug from the bottom of the tranny case. Adding tranny oil is done through the clutch inspection cover or chain inspection cover on the left side of the bike using a funnel with a hose attached (sold in aoutoparts stores everywhere). Tranny oil and engine oil are not the same! I would use Sportrans or HD tranny oil for that instead of 20W50 in the tranny. Add no more than 28 oz. If you add the whole quart (32 oz) you will have hard time finding neutral as the case will be over-filled. If you take the clutch inspection cover (a.k.a. derby cover) off, make sure the bike is not leaning on the kick stand but is upright or the proper amount of oil in the tranny will spill out. I put a brick under the kick stand and it centers the bike pretty well.

Good luck!
