I've seen a lot of the European bikes with different types of bottles used for their over flow tanks. Can you buy these or how would you go about making one. I'm currently turning a 2000 zx7 r into a streetfighter and the right side of the bike looks like sh*t with all of the coolant hoses, etc. I was going to try and hide it but I can't seem to make it fit anywhere. If anyone could offer up some advice that would be great. Thanks in advance.
