beginners guild to suspension setup wanted

[khabel]

Does anyone have a good beginners guide for setting up suspension?

I have a 95 KX250, 6'3", 125kg. I'm pretty sure I'm going to need a heavier rear spring.

Yeah you need about a 5.4 for your weight and height. Stock is about a 4.9. The problem is the front where you need .51 fork springs. Stock is .39. You might have trouble getting those. The highest rate that Race Tech list is .46. Not sure about Kawasaki.
