My bike was stolen a few weeks ago and when it was recovered I’ve had a few issues with it. The ignition wires were cut so he could hot wire it, the battery was drained so I got a new battery and instead of getting a new ignition switch I just rewired the switch wires soldered and covered them with heat shrink. I took it for a ride and started off good but I make it 4 blocks down the road and when I come to stops the bike dies. Could this be to a not so good connection in the switch wires? Or a different problem?
