Gettysburg, 2008 Tour Premium | Does anyone have information of the weight of the Victory Carterage Fork Oil? Would like to do synthetic at change time and Amsoil is either Light (5wt) or Medium (10wt).

New Bohemia, VA | I tried to find it on the bottle and could not. I'm curious on different types of oil for the fork as well as the Victory Fork Oil is at its useful limit when it reaches the recommended 15,000 mile change.
I had 30K on it when I did the 45K miles service and it was refreshing to regain the front end stiffness. I asked a wing friend as they use fluid also, he said he had over 100k with no problem??? I'm just wonder if he is just tolerating the softness or is there a different system for the 2003 GL1800.
When I asked my dealer tech as to what oil could be used in the forks his reply was to question why I want to use anything but the designed oil from Victory for the forks. |

Newberry, Mi. | The fork oil in the Vision is 10wt. Each fork tube will take about 540cc's and the bottles are usually 1000 cc's. This information is from another Vision forum. |

New Bohemia, VA | well, I didn't know the weight but the book calls for 330cc to put in there to bleed, then bring the level down to a certain height. I woud guess it actually holds around 300cc per fork. Just did them and followed the book for the measurement. |

LOL!
OIL THREAD, OIL THREAD!
I use only fish oil in my forks (if it was good enough for Soichiro Honda then it ought to be good enough for me).
In addition to being a great lubricant with viscosity fade resistance, its also is a good source of omega-3 fatty acid and will help keep my front fork springs from losing their memory and getting mushy.

| I just had mine done a month or so ago and quite frankly don't feel any difference. Of course I'm going to redo mine as I don't believe the dealer did them correctly, in fact I kno they didn't but thats another story.
I'm curious about how the 10wt number came to be known since Victory wouldn't even tell my dealer? They simply said use the Kingpin oil pn#........ I'd like to know before I redo the suspension this fall. My guess is it is more likely lighter than 10wt since the bike uses a cartridge. I might even reset the sag so the bike doesn't drop into the stroke quite as far and go with a 5 or 7.5 oil. I prefer the front a little stiff and a little high (from my dirtbike days).
As to the longer interval? Bear in mind that motorcycle manufacturers base service interval on the average rider. That would be like 2500-3500 miles per year. So the 15k interval is just a recommended oil change based on use, and potential contamination. Forks like hydro clutch are contaminated by heating and cooling causing moisture buildup. Unless you have some reason to change it at 15k like maybe it feels soft or busy...., you could likely run much longer between intervals. Most bike manufacturers don't even list this service. I know some guys running other models have gone with Gold Valves but I don't see any real need for that on the street.
Me? Well I'm going to do some more inquiring about oil wt and see what I can find out with some certainty. I'll play with it from there. |

San Antonio, TX | Tarpits99,
Sounds like the makings of a "fish oil for forks" video.
I can see the comments now. "Why does you Vision smell like that? Don't you wash it?"
Seriously,
Amsoil and others make synthetic fork oil. I know there are Amsoil dealers on the forum here that will tell us the proper part number from Amsoil.
