Thanks Twowheels for the info. So buy a good quality socket and then grind it down past the chamfered edge so it's a tight fit on the base valve. Got it.
Pics of the cartridge holding tool would be great. Now to find someone to make one up or sell me one. Anyone over that side of the ocean got one for sale? Ill ask round local tuners here surely someone will have one.
Already got the 7mm shims sorted. Thanks Simmo
Also a local tuner sells them. The main aim at the moment is to get them apart without breaking them and attempting to figure out how it all works along with current shim stacks. After that ill ask for some opinions and change stacks to suit.
Re the practice, a mate will be diving into his KTM 300 WP forks very soon so ill pay attention.
Thanks guys
