Well, I noticed a big improvement on Miss Whiplash's front end just by taking out the thin grey wee and pouring in some nice fresh ATF.
After that you're looking at making up some spacers, you could try getting a big bag of the right diameter washers from B&Q or wherever and adding them one by one until you're happy. That will give you the thickness you need to make up a permanent spacer, or you can just leave the washers and add/subtract depending on how you want to ride.
You're welcome.
