Question 1: Maybe

Question 2: The bargraph should be showing what is going on.

Put the jet in a container, like a 500ml water bottle, and put in test for 1 minute. Measure how much is there and look at the jetting charts.

To tell if it's the low failsafe limit. Get in a high gear and very lightly roll on the throttle. If the bargraph moves and the yellow light comes on it's probably the low setting.

The gauge should have been set for 6 of 8 bars when initially configured. If it's hitting 8 bars then it has a leak.
