@Mayhem and manchillz. Thanks I found some info on the net. Seems I need the WC solo air spring and air top cap. I managed to find part numbers for them, is it something I can get from SA supplier? With regards to the fork stantion, apparently if you swop the right to the left, then there shouldnt be problems with damage from the spring? What do you think? Also found a full conversion kit, retail for 100euro, made by Protone from Italy. Anyone heard of it before? Anyone seen the Elka Stage 4 pressurized fork cartridge before? Coming from Motocross, it sounds so cool! Would like to speak to someone who has had it done or ridden one.
