Ok, here's the deal. I have a 1993 Kawi 600. Just had alot of work done to it to make it reliable, but it has gremlins. Got it back and it ran great for about a month, then it would randomly die on me when riding. It would take about 5 minutes but it usually fires back up. Now I can crank it and it will run for about a minute before dying then it will just crank but not start. It appears not to be getting gas, because I can unhook the tank after attempting to start it and less than a teaspoon of gas is in the line. I had the fuel switch replaced but the problem still exists. I have been checking and replacing vacuum lines in an attempt to get it running but nothing. Does anyone have any idea what it issue could be and where I should start looking?
