Please allow me to introduce my 95 Bandit 250, pictured. I recently purchased it and gave it a muffler (Danmoto for 600, expanded the midpipe to 2 inches) and some Rizoma bar end / mirrors and a new tank pad, Sport Demon tyres, a few other things. It came also with dirtbike handlebars which are pretty wide. Mothers Back to Black made a big difference to all the black plastics including the seat. Before I take it out for a ride on the new tyres, can anyone tell me what I should fill the little white plastic bottle with (second picture)? Looks like cooling water to me but I wouldn't want to get it wrong and I don't have a manual...
