SOURCE: TRANSMISSION SERVICING

Most are using Syn3 oil in engine, tranny, and primary.
This simplifies this, and is a decent oil.
32oz of oil in primary.
20-24oz of oil in tranny
99851-05 primary case/ trans oil(Conv Oil)

there are other brands that surpass the syn3 oil but it takes some hunting around to find a supply.
Ammsol is one such brand and they recommend.
20w50 engine
15w40 primary
75w90 tranny

Hope this is of some assistance

Sounds like the previous owner didn't get the cpu remapped, Take it to a Harley dealer and have him check the exhaust mapping on the cpu, Shouldn't cost much or if you want get them to fully service it so that way you will know were your at with it and will have a reference point to start with or service and maintenance reasons (and re-sale value) Hope this helps

SOURCE: My 2003 harley ultra classic has cruise control

On your throttle cables on the left side of the bike at front of the bike just ahead of the gas tank you will see a "bulge" where the connector is for cable position/sensor plugs in. check this connection first, clean it, etc. plug things back in and test it.
Please post and let us know if this helps.

I'd be careful with the heli-coils. Once in they can really be a problem to get back out once they're in place and go through the heat and cool process for awhile

Hi, Patrick I just read the comment you left me it appears there is some confusion about the gasket in question are you talking about the top engine gasket (rocker cover) or a tappet block gasket or a transmission cover gasket and do you have a service manual? For more specific information or questions at no charge please feel free to contact me at xlch@mail.com. Good luck and have a wonderful day.

My 2003 hd ultra classic is leaking trans. fluid at the top of the trans. what do i do?


first spray it all clean with brake parts cleaner, careful not to spray on starter. then start it up go around the block and verify where the leak is, if its the top cover get a gasket replace easy fix five bolts. now if your leak is coming from the nipple or short hose thats on the left side of top cover thats a vent and this indicates the tranny is over filled with fluid.

My 03 ultra classic is leaking trans fluid they say its a $1 dollar o ring that cost about $600 to fix?


First off, determine if it's transmission fluid, or primary chain case fluid.
I had the seal on the transmission main shaft go on me once (the seal under the transmission rear drive pulley, behind the inner primary cover).
This can be changed with the transmission still in the bike, but the entire primary needs to come apart, and the transmission sprocket/pulley removed to access it.

If it's primary fluid, it's probably the seal on the inner primary case that the transmission shaft runs through and that the clutch assembly bolts to.
Again, the entire primary needs to be torn down to access this.

Either way, the cost of the part isn't bad, but the labor is the killer, as it's a 6-10 hour job, if I remember the book's quote.

My headlight goes bright for a few seconds on a 05 ultra then goes back to normal.


There is a wiring problem.

Check first to make sure that the wiring is not shorted out anywhere in the lighting harness, then chack that all your grounds are connected well, not corroded or broken

this is the most commom causes for your problem.
