Hi I'm considering buying the nylon BB's since one or two of my stock XL shocks have sprung leak. It's silicone oil you use for the shocks? How much do you use to fill the 4 big bores? more than 60g (2oz?). I wouldnt mind maybe doing the fuel tube mod and lowering it maybe abount 1inch? But then i would need harder shocks so it doesnt bottom out so easily?
