Im looking to run one petcock instead of 2, have any of you guys expirienced running 1 petcock on a 4 cylinder? Any starvation issues? My bike is a 79 XS1100. Thanks

Shouldn't have any issues... Pingle actually makes manual replacements for those things... just don't forget to plug your vacuum source on your carb boot.

I welded in a bung and installed an old Harley petcock that I found in the trash on my KZ1000. Been running it that way for about three years.
