I just recently bought an 87 zx750r F1 and, I am trying to ressurect it. It was recently running after I put it in the shop for a carb sync, back tire, idle gear and starter replacement. In its previous life someone removed the stock air box and replaced it with the K&N cone filters, so I have a lot of hoses sitting in there connected to nothing. Last night I pulled the tank off to tighten the bands on the air filters. When I removed the tank it only had one small line going from the petcock to the carbeurators, and there was no gas spilling out of the petcock. I set the tank on my drive way carefully and the next thing I know gas is running out of the large nipple of the petcock. When I press the button on the petcock( which I assume is some sort of prime button.) the stream of gas gets larger. I have the small line going to a nipple on the topside of the carbs and there is a large line coming from underneath the carbs. Should this go to the large nipple on the petcock? I tried that and the bike wouldn't start. Is it because I didn't hold the prime button in before starting. I've looked at all the parts diagrams and cannot find anything on the routing of the fuel lines in a repair manual. Could someone please help me with this.
thanks
