right i think i'll have a go at changing the oil when i get some spare time then. Thanks.
I put 15W in my bike 18 months ago. I think the difference is astounding. And for that kind of money, its a well worth while job.
Best way is by measuring the air gap at the top to make sure they're both even.

You wont need more than 1 Litre of fork oil. The actual amount needed per side is mentioned in the Haynes or workshop manual-check the downloads section on here. From memory its 400 AND SOMETHING ml per leg-actual amount varies with model year of forks fitted.
1 litre should do it, but there isn't a lot to spare, so don't spill any.
475 cc for 98 and 99 ,, 2000 on 465cc per leg

I've never had a front end problem that many here have experienced, but I had a leaking fork seal so had to change mine the other week (along with a kebab-supplied R6 shock on the back). The first thing I noticed was that the oil that came out was in excellent condition and very, very thick. Much more so than the 15w I put back in. There is no noticeable difference in the front end since the change and I wondered if for some reason fork oil thickens up as it gets old?? Mine had been in for at least 35k miles.
