Is anyone able to tell me the proper method of measuring & refilling front fork oil for an 03 pro 250 and an 04 pro 280. I beleive you can measure down from the top of the stanchion tube to the oil level but I am not sure if this is the recommended way.

What weight of oil (for both bikes) does anyone recommend.

Thanks

On these forks it is normally a volume measurement used. If I remember correctly a starting point is 300cc per leg. 5wt is generally standard.

Some very meticulous folks (read: Jon Stoodley ) allow for variables in how much oil draind out during a change and prefer to measure the height of the oil.

Check his tech tips on the GG website.

There might be a spec.
