cheersTo help you rule out fuel starvation from the petcock or tank venting try running with the lid open and the petcock on prime, don't forget to switch it back to the "ON" position after your done testing. Mine would run out of steam around 110mph because of a combination of the two. It also caused surging at highway speeds.

Look for kinked fuel lines!!
