Does anyone know what "weight" the stock front suspension on a softail would be? I want to stiffen things up a bit (or slow it down) and don't know where to start. I seem to bottom out too easily.

Perhaps it isn't the oil, but maybe the inserts are shot?

Just had the forks redone so I believe everything in there is fresh and ready to go. Ok, so I'll try 15W.

NO!!!!! Don't try 15W right away!!!!!

Trust me on this one. You want to go up in increments. After the harley 5W stuff there's a 7W that you can get on JPCycles.com. Then there's a 10W, a 15W, and then some Harley racing fork oil that's meant for tracks. I've tried them all, and like you I've never found that sweet spot, that suspension "G" spot if you will (IMG:http://www.harleyshoptalk.net/forums/style_emoticons/default/whistling.gif)

Right now, after dabbling with the 12W stuff for a season, I'm trying the 7W stuff again. Good luck but I do think you should not jump to the 15W right away. Just my personal experience.

How difficult is it to change fork oil?

You got brass drain plugs, right? Drain the old oil by removing those. "Pump" the forks to pump out all the oil. Replace the brass screws. Remove the top caps and refill with appropriate amount. Isn't that about the extent of it?


Some guys use a vaccuum pump. After draining they draw vaccuum on the fork and suck up the appropriate amount of fluid then quickly replace the brass plug. I think that's the basic operation. Never done it that way.


Should not be too awful bad on a Heritage. Lot's of guys HATE that job and always hire it done. I have progressives. Good for about 50k but I'll not likely stretch it that far.

That's about it....

I removed the top filler caps and then drain.... Replace the drain screws and refill with I think it was 10oz in each fork....

Good Luck...
