Re-valving dampers

If I want to consider trying this, where should I begin? And, is the type of oil used in dampers a consideration as well?

From my experiance there are a number of shock absorber firms that can't even build two that are the same rate. And presumably they have the equipment ! you might consider it , but reading what you say on your post as regards oil, I would advise you don't do it

Yes, Motor bike raceers I know "tune" shocks with differnt oils, I believe Motul have an extensive range available.
But I can't answer any more than that as I send mine out to be done.

For one its pretty hard to accuratley valve shocks without the use of a dyno....even though I admit I do at times throw shot in the dark stacks together I would not reccomend some one just learning do it. It's like setting tire pressure with your thumb.

If you just want to have the valving changed I would reccomend you have them serviced by a competent shock specialist.

If you want to learn about how to do it yourself....I would start by downloading a few manuals from Penske's site and attend one of the shock courses offered by either Penske or ohlins.

As has already been said,Bikers do "tune" thiers by using different oils,Rock oil being the favorite.Its a case of looking thru the list,but you will have to experiment to find what suit,s your application but Rock oil takes more of a pounding than the conventional shocker oil.

Okay, all good advise. Yes, I want to learn...but I also realize that most folks tuning dampers have dynos.

The most important thing is to be very patient and take your time. Make sure you get rid of all the air bubbles, it takes time and you think you can take liberties but just dont. Make sure you have a very clean environment and keep your oils contaminent free.

Absolutly,it is probably best to leave freshly oiled shockers to stand for a good few hours before refitting the Filler bung.
