i mite just carry a ligher around with me incase of it freezing but to be honest i dont see how it can freeze as your forever pulling the bk brake so the water is constantly moving and if you keep your bike inside while your not using it surely there will be no problem..
too be honest i dont think i will ever use any kind of oil again even if it dose bugger up the seals there no problen for me to get hold of beacuse my sisters b/f has a box ful of them all different sizes and i just put a new seal in befor i bled it.. oil is :lol: ^_^
