(2003 reg K1 ) I have just replaced my fork springs etc with hagon progressives and 15w oil - feels well planted now.
Like you I was fishing round for an 'easy' way to do it as I haven't attempted it before. Finally I did take out the fork springs. It was quite easy apart from the fact that the caliper bolts were in solid and I had to make a trip to halfords to get surface gripping sockets (6 flats) to get then out (and similar for the wheelnut too) after I had taken the corners off with an ordinary 18 point socket..
You need something to lift the front end off the ground. After a mishap to do with an idea of suspending the front. I borrowed a headstock lift from a mate. (I know about abba stands thanks)
With the correct spanners/sockets, removing the forks is quite easy. Make sure you loosen the big FLANGE bolt first though. Tip the old oil out into a suitable container and then fish out the spacer, washer and old spring. Try to ensure that the fork tube does fall to its full compressed position or it will tend to stick - you have to get a good grip on it and yank it hard to get it back out.
With hagon prog. springs the air gap is 140mm. For some unknown reason (probably a CRAFT symptom) I left a 150mm air gap, which is approximately 12cc too little oil. A 10cc syringe is an invaluable tool
One word of warning: don't do what I did which was to take the front wheel off with the bike on front (and rear) paddock stand. The nearside fork rotated slightly and nearly fell off the stand. Fortunately I had taken the precaution of looping a tie down strap around the handlebar and a beam in my garage.
That was a bit of a ramble I guess - hope you got the drift of it .
