its time to do the first oil change on my new to me 2009 nightster. i been searching and cant find out good oil for it and also for the tranny. and also is there a good write up on how todo the oil change and tranny change? thank you in advanced i do the oil change on my truck and atvs so i fig the harley cant be much diff..

 

Get yourself a Sportster service manual if you are going to do your own work.

But the owner's guide that came with your bike should have basic oil and transmission change instructions in it too...

 

Living in Florida where it is hot most of the year I'd consider synthetic for the engine, it'll do better with higher temperatures. The mechanic at my dealership recommends just using the regular Harley tranny oil. The biggest thing is to use the correct viscosity for both. As far as brand, well that could start a whole debate.

 

Get to your local NAPA auto parts store BEFORE Friday (7/1) and pick up some Mobil-1 15w-50 synthetic. It's on sale for $4.99 / qt. You'll need 3 quarts, but at that price I'd pick up some extras. I just bought 2 cases... LOL

Also pick up a quart of Mobil-1 75-90 Gear Oil for the primary/tranny. If NAPA doesn't have it, Autozone usually does, ~$9.00/qt.

In addition to the Service Manual, I recommend the Fix My Hog DVD (Sportster Edition), as it walks you through all the standard service procedures.

 

Remember, when changing the tranny, don't mix up the drain plug with the chain adjuster.

 

ok thanx for fast respons, u can use reg oil in these motors u dont need motor cycle oil?

also some people say u dont need to chang tranny fluied till 10,000 miles but some say every other oil change and some say everyoil change i orderd the service manul today so i am gonna be good i hope... also got bike used and did not come with owners manle

 

i run syn in mine. don't you have the owners manual? tells you how to change the oil step by step. piece of cake.

 

I've been changing my engine and tranny every 3000-5000.

 

The owners manual for my Nightster says to use 20W50 for synthetic, and 10W40 with multigrade oils.

 

Reread the manual.....
20w-50 and 10w-40 are both multi-grade oils.

10w-40 should be used when the lowest ambient temperature is BELOW 40*F
20-w50 should be used when the lowest ambient temperature is ABOVE 40*F
