I have always favored 4-strokes because I like riding tight woods and always found the low end torque to be an asset. I have noticed however on the WR that when I'm in the real slow stuff that lugging the engine in 2nd and sometimes 1st the bottom end makes some discouraging noises, knocking mostly. How much damage does lugging the motor cause? Also, I have disconnected the gray wire. Will re-connecting it give it back some low end grunt?
