Never done this before 79 GS1000L

I didn't see an answer to the points/condensers suggestion. Do you still have them? I wouldn't expect intermittent fuel issues to recover with the surges you described.

Hello all,

I have very done little to resolve my problem but haven't been riding either. I did ride to work today and the same thing happened but this time worse the engine completely died. I quickly got off and could see the fuel filter was empty, took off the gas cap and started cranking. I could see gas coming back in and after a little more cranking the filter was full and all was well, put the cap back on and made it home. Not sure how the petcock works but it apparently is not working as far as letting air back in to displace the fuel. Any recommendations as to the best way to address making my petcock as new, money is not really an issue but needs to be well spent.

I do want to add that I don't know if this is the problem for sure, just my observation and result.

Thanks

It is not your petcock that lets air back into your gas tank. The air is let back into the tank by vent holes in your fuel tank cap. Check under the cap around the gasket and you will find the air return holes.
