My son’s Dragster was running great minutes before replacing the front brake lever and now the bike won’t run. It powers on but when the throttles engaged, there’s no power, no noise…. nothin.

I originally thought the sensor may be engaging some sort of kill switch but even when I disconnect it, the bike still won’t power when throttled.

Any suggestions?

PS: I noticed this plug coming off the throttle was not connected to anything prior to the bike acting up? Anybody else have the same? There’s nothing to connect it to…..
