The stock springs are unbelievably rubbish. Linear is a better choice if you mainly ride solo, progressive can be useful if you ride a lot with a pillion. I would go for 15W oil. Changing the oil can be a pain, strictly you should take the fork legs out and tip them up, but there are threads on here about a sort of suction tube instead. Support the front end, take the fork cap off, remove the spacer etc., suck out fork oil. Replace oil and get the air gap right - about 105mm I think from memory, with no springs and the fork leg fully compressed (which is easier to do with the forks out, or at least take the front wheel out so you can push them up and down individually). Changing springs is simply a case of taking off the fork tops and pulling the springs out. If you don't already have the preload adjuster tops from later curvies them this is a good time to fit them.
