Whitty

Is the fork service DIY'able or do you need special tools? How do you know which oil and how much to use? Don't fancy tackling shocker though, how much for you to do shocker? I am a mechanic but on buses so have plenty tackle and haynes manual at my disposal(if not maybe a bit big for bikes). I have always had near new bikes in past and not really had to mess with them apart from oil changes etc. I deffo want to fit new springs front and rear, I am on the right track with linear ones for track day use? Whos are the best value? Where you at? Sorry about barrage of questions!!
