I am working on putting my 1987 650sx together and noticed that I don't have a stinger to waterbox exhaust hose. Is there any reason I can't just use some radiator hose? If radiator hose works, I need to know how long the hose from the stinger to the aluminum 90 degree fitting is. Looking at how everything is laid out, I'm pretty sure I need to get the waterbox side of the hose secured before I put the fuel tank back in.
