GPZ500 (1990) . i took it apart to see whats going on under the bodywork. I took out the carbs and cleaned them. When it was time to put everything back together i ran into a little trouble.
1. On the carb there are 2 rails with one nipple on each rail. My question is: does the top rail go to the fuel tank? and where does the bottom rail tube go?? or is it the other way around. (you can see the bottom rail with the yellowish tube on it)
2. If you look at the pictures, What is that round thing (one bolt holding it in place and has a round rubber gasket on the other side) with the hole?, what is suppose to go in that hole??
** ive taken a close up of this round thing and then the rest of the pictures are taken further back so you can see where this round thing lives.
