I find that in normal braking the front forks of my 2008 Ultra seem to be very soft. I am looking to stiffen it up and have the following questions. Will changing the fork oil help and if so what weight of oil are you using? Also, should I consider new springs, if so any advice on a particular spring to use?

Thanks and enjoy the Memorial Day Weekend. It is those that serve that allow us to ride FREE!

 

Progressive springs will fix that, 15W oil.

 

Fork spring changes.

 

Thanks for the responses. Regarding the progessive springs, is that from the manufacture "Progressive Suspension" or another manufacture?

 

The middle grade fork oil will help. the se oil, but not the heavy.

 

I fitted progressive springs on my bike with 1 3/4 spacers and 10 weight oil no diving under brakes or dragging floor boards on every corner now. Progressive suspension sells the fork springs also check out there stabilizer brace for your 08 bike

 

That will help. Still not like they should be, but whatever you do, don't waste your money on the race-tech gold valves. I'm heading this way-

You might try SE Heavy (not Extra Heavy) fork oil before investing in aftermarket springs. I have it installed and it made a big difference, firming up the front-end and reducing bottoming and dive. It is an easy job if you follow this procedure.

 

Yes, Progressive Suspension springs. Best bang for the buck for front forks.

 

Technically speaking changing fork oil can not change the amount of dive, it can only change the rate that the front dives at, if you follow my drift. Oil weight controls damping, it can not reduce the amount that the suspension compresses for a given force.
