If they are Ohlins.
Here is what was on the package that I got.
Honda CR125R 97-07,CR250R 96,CR500R 96-01, Kawasaki KX125 96-01, KX250 96-01,KX500 97-04,Suzuki RM250 01-03,Yamaha WR250E 01-04, WR250R 01-11,WR250X SUPERMOTO 08-11,WR400F 98-00, WR426F 01-02, WR450F 03-04, YZ125 96-03, YZ250 96-03, YZ250F 01-03, YZ400F 98-99, YZ426F 00-02, YZ450F 03.
They were MSR Seals P/N 41-3926.

Make sure that you heat the tube to expand the metal for easier inner tube removal. The guy I talked to at Ohlins, was very clear about this part. It does make a difference.

I can't remember how much ,but I use a fork oil gauge. Also I have found thet Mobil 1 synthetic ATF works best. It is about a 5 weight.
There is a Cannondale fork manual out there. Download that for help. Page 12 tells how to fill. Specs are 90-130 mm from top of tube.

Any auto trans fluid will work. The mobil 1 was just recommended about 10 years ago and it works well. ATF is about 5-7 weight.
Jeremy Wilke was a contributor on Dirtrider.net and he was also the owner of MXTech that did suspensions. That was his suggestion. He mixed mobil 1 with something else,but would never tell what the other was.
I still use it ,but in a pinch,I would use regular automatic trans fluid.
