Dose anyboby know af anywhere around london that overhauls/rebuilds forks I have one seal leaking so I was thinking of getting better internals as well or is this a difficult job to do without special tools. I am fairly confident with mechanics will have a go at most things but this sounds trickey
If your reading the manual, everything, including a simple oil change sounds tricky.
Assuming these are not trick forks with too many bells and whistles, most are about as complicated as a cycle pump full of oil.
Just a few rules. Never remove the legs from the yokes. To get things back together and perfectly in line is a devil of a job if you do.
Do one leg at a time and if you come up against a problem that needs a special service tool you can’t work your way around, stop, put things back together while you still can and take it to a professional. Preferrably a specialist.
In S E London that will be Perry Leask at H M Racing at Green Street Green. 01689 859211. Expect to wait a while for a booking. This guy is seriously good and all the local 'crossers and prod. racers know that and use him.
Best of luck.
i got my seals done at DMC, dalston motorcycles 02072492360
or there is essential rubber, 02072410055 both are good places & the prices are good
If you’re pretty confident with mechanical stuff then forks are a piece of **** to strip and rebuild.
Dunno about leaving them in the yokes - I’ve never had problemas after taking forks out of the yokes
Fork rebuilds are a piece of cake. 
Just make sure that you take out the allen bolt at the bottom up inside the sleeve, the one that holds in all the plungers etc, with care. If you take the leg into any mechanic shop they’ll put the air ratchet on it and remove the bolt for you. Don’t force it or you’ll strip the head, after that no problem.Something that they didn’t tell me in the manuals, or I missed :D. When you put them back in ensure they are both in at the top of the yoke at the correct height and EVEN. Tighten the top clamps. Put in the wheel and reassemble as normal and the very last thing to do is take the bike off the main stand or paddock stands, so that it is free standing, sit on the bike, with the front wheel facing forwards, pull on the front brake and bounce the front end up and down 2 or 3 times. Then tighten up the bottom yokes. This lines up the forks and wheel with the back end. Otherwise the wheel and forks will be off line and you will get a very interesting ride especially when you brake.
Best of luck

although it relates to mx forks the principles are basically the same.
