[Hoist!]

I have not used the Amsoil as it is only equivalent to a 5w or 10w oil. 15w is what I have been using......

I'm with Jim and Ernie. 15W PJ1. Amount per your manual for your bike, No cold temp problems. Front end more responsive. No fork seal leaks. Overfilling will cause fork seal leaks. Hoist!  8-)

Have had the 20w SE oil in the red bike since it had 1000 miles on it (give or take a few).  Really needed it as stock it bottomed out under heavy breaking. It is firm now.  But I prefer it that way.  So the difference is very much one of a person's own preferences.  Mind will likely get changed again before this spring overtakes us and I'll stay with the same thing.  It's not been an issue in colder weather.

I too have the 20w SE oil like Don. I am very happy with the performance in handling. Before it would bottom out. I ride year round in temperature ranges from 20-100 degrees and haven't noticed any concerns.

I just did my 20K service and changed the original fork oil. I could not believe how it looked and smelled. It stunk up the garage so bad I had to air it out. If this is normal it should be changed a lot more the the 20K recomendation from the MoCo. It reminded me of some kind of fish oil.

Same thing here. It stunk soooooo bad that Kathy had the dog sleep in the house instead of the garage.

Will be changing the oil every 15000 or sooner from now on.

Sooooo... they put Syn3 in the forks now??

i changed mine today at 17500 miles. it was a lot easier than i thought it would be. per hd dude i used 15 wt oil. ill go out and do some wheelies and see how they feel. p.s. the old oil didnt smell bad- also put on the tour pack fairing with led light. looks cool!! [smiley=banana.gif]

I admit I am ignorant...when it come to this...so here I go.
Ok the Syn 3...are you talking about (20w50 SE Syn 3) the one used in the motor...or something else.

Is this a big job or can someone explain to me how to do it...
I would love for my front shocks to be a little stiffer...
This could be a good project for a rainy weekend.

Thanks,
Barry

On the Road King it is very easy all you have to do is pull off the headlight nancelle, and just drain and refill. On the FLHT's you half to disassemble the left fork to drain the cartridge, which would require front wheel and fender removal. I think they are joking about the syn3. Use fork oil. Although my 75 Norton 850 Comando specify's 10 w 30 motor oil in the forks.

Barry...no, it's not syn3...it's special fork oil you can get through HD and it's just called SE Fork Oil, but it's a straight 20W oil.  The 15W mentioned is not HD fork oil, but other brands.

Can't help you out on the change as I have not done one (yet) myself.

Terry,
Did you use the racing performance SE fork oil? john

Have not changed mine...yet.  That may be something I do very soon though.  I think I will go with the 15w though and see how that feels.  I would like it a bit firmer, but not too much so.

Thanks Terry, Don said the performance SE fork oil is the 20W. Since I got the legends on rear the front performance is more noticeable (or lack there of). So anxiously awaiting word on cartridge system ( also trying to get more information on emulators!) thanks john

Know what you mean there, John...the Legends seem to make the bike handle a lot better, so it makes the weakness in the front end show up...I'm feeling the same thing!  Waiting to hear from Don on the fork rebuild he's helping he guy with in the other thread...

I know what I did violates some law somewhere, but when I put the Race Tech Emulators in my FLHTC, they recommended going to a heavier weight oil, like 20 wt. Fork oil is hydraulic fluid, plain and simple. There are anti-foaming agents and stuff like that in there, but in the end, hydraulic fluid.

I went to my local jobber and got 1/2 gallon of 20 wt fork oil for some ridiculous price of something like $2.00. We just went out to the huge tank next to the train track and he filled up the jug I brought.

On that front-end, I added the emulators, went with stiffer springs and upped the viscosity. Those changes made the bike extremely sure footed without sending you to the dentist for new fillings when you hit something you wish you didn't have to.

How long did it take you?
I am just over the 20K mark and thinking of doing this with 20w SE real soon.
Hopefully it will help me out until Winter Storage in Maine, coming soon.
In the spring i expect to go to progressive mono shock tube.

Thanks
