I found out the reason that I've got a big pool of gas under my bike. I seems it has something to do w/the leak in the fuel system. Imagine! Well it seems the problem is this line leading out of the cutoff valve to I-don't-know-where (strangely, there are 2 lines going out of the cutoff valve. One to one of the engines, and this one). Oddly enough I can't find anything in my Clymer manual telling me what to replace them w/. Can anyone tell me? It's also got these little metal clamps wrapped around them.
