:agree: I had a "no start" condition wiith my ride. I pushed it home , filled the gas, checked for spark, replaced the plugs, etc, etc. I finally got serious with the vacuum for the petcock. Mine was loose at a "T" fitting behind the petcock under the tank . I would suggest looking to see if you might have other connections for the vac hose that you might not have checked. It can appear to be attached, but if it comes apart easily when you give it a pull, it is not getting good vacuum to allow gas to flow. Hope this helps. Good luck.Check the vac line on the back of the petcock. If it's off you won't get fuel.
