Fuel Petcock Screens

Since my stumbling, lurching issue started, I want to test if this was a fuel flow issue.

The Test Ride
I went for a short ride, various speed, after about 10 mins, the bike lurched, and begin its usual crappy ride. I pulled over, gave it about 2 mins for carbs to fill back up and continued on. I rode another 10 mins, and the bike still was lurching, this time I had only one petcock on, the left, I quickly reached down turned it off, and pulled over.

The left carb bowl was about 1/3 full, and the right about half. I left the petcocks on, and it would not start, until I let the bowls fill back up. At this point the carbs are not synced, so it might be running lean or rich, but it did seem as though my issue is fuel flow.

Fuel gas cap is venting, so I decided to check the new petcock screens. I proceeded to let the bike cool off, and then drain the fuel, the left side seemed slower than the right as the fuel flowed out of the petcocks. I cleaned them out,, there was some red flakes coming out of the petcock tops, and reinstalled minus the small lower screens. I left the top straw screen on, since i know the tank is flaking a bit.



This tank is due for flush out, repair, and paint, but for now I will try riding without lower screens to see if this helps.
