Runs while leaned, not while upright.
Why would my SP1 start and run fine while leaned over to the left / on the kickstand but sputter out when sat upright? The bike is in neutral and the kickstand safety is disabled. The gas tank looks clean as ever and the fuel pump strainer looks great.
The bike was run dry of fuel by a friend of mine just prior to this issue. I put two fresh gallons in it and had no luck.
