Hello so I just got a Yamaha bear tracker and the original owner swapped the motor to a Timberwolf of a different year so he cut the plugs off the stator to wire it into the bear tracker harness I have spark and everything but it runs poorly like back fires won’t rev up. Some wires that comes out of the stator isn’t hooked up also and I was told it won’t run right because it has a bear tracker cdi and regulator
