fork oil/springs

this week i removed the oil in the front shocks. the old oil looks like trans fluid. I'm looking to get a softer ride. on this site i read that the oil is 15wt. what oil can i put into the shocks to achieve the desired effect? if softer springs are the answer then where is a site to order them suzuki has no springs to replace the burgman spring other that original.
i have the dimensions in U.S. .185 wire dia. 13 11/16 overall with 4" closer wound. 1 3/8" total dia. for anyone interested it this for research.

Sorry Jim, I got called away. The bike has 5,824km (about 3,000 miles).
Never ridden in the rain. Only washed by hand (no power wash).

If you go to a lighter oil I would guess that the bumps would be felt even more at higher speeds.
well i put in 5wt fork oil and it did nothing for the ride today. looks like the heavier oil is the way to go just what wt did you install alwalk? it is not hard to replace. but i want a smoooooth ride and not one that just about throws you off the bike. like others on this site the burgy has way to hard a ride for a scooter. i miss the helix ride alot. thanks bob p

I installed Bel-Ray 15 wt fork oil and the ride improvement was incredible. Definetely try it. If 15 doesnt work than try 20wt. BTW when I did my fork oil I weighed around 200 lbs. , just to give you some idea of the bikes load.

Watch those spacers!

OK - a word of warning. The fork oil replacement job is fairly easy, except for one step. The tricky (and dangerous) part is getting the caps back on the forks. You really need 2 people for this step. I sliced my thumb wide and deep when the cap slipped and the super sharp metal of the spacer shot up and attacked me.

Here is what to do - Put the bottom of the fork in a vise. Have an assistant hold the slider tube up and also keep it from turning (preferably with a pair of gloves on). Somehow position your body atop the fork and tighten the cap with a straight down motion to prevent cross-threading. Once you tighten to the point where the slider spins despite your assistant trying to prevent that spinning, you are done.

Also - Good luck finding the 12mm and 17mm hex heads!!! I looked all over town and finally found them in a 3-pack of 12, 15 and 17 for $7.99 from AutoZone. Sears didn't carry any bigger than 12, and this was a big, ugly Allen Wrench for $9 and change. No luck with Parts America.

Suggestion - get these hex head tools before starting the job!

I installed the fork tubes in the steering head (triple tree), and tightened it up before I installed the cap. That way you only have to push it down an inch or so, and you don't need the assistant.
