Hi I just bought a 2004 cr250 that has showa dual chamber forks and wanted to change the springs in the forks back to stock since they had heavy weight springs in them. And I didn't have any fork oil so I was trying to do this without losing any oil, but I lost a bit of oil in the cartridge and now the the bottom of the cartridge where the base bolt screws into doesn't want to extend. Every time I pull on it to extend it it gets sucked back in the cartridge. Is this an issue because I don't have enough oil or I need to bleed them??
