Can a single cylinder crankshaft be balanced? Does it help?
A single cylinder crank is always unbalanced. The balancing operation we perform moves that unbalance (vibration) to an RPM that is either higher or lower than your engine’s RPM operating range. We accomplish this by removing or adding weight to the crank in a location that our balancing equipment has told us to do so. Balancing or “moving the unbalance” really helps a single cylinder crank, especially if it is to be used at sustained high speeds. At Falicon, we balance your crank for its intended use and RPM range. But the XYZ Crankshaft Company says that even if my crank is cracked it will still work! Yes it will, but since we do not employ any psychics, we cannot predict when it will fail and if anyone other than your engine will get hurt in the explosion. Falicon will NOT repair a crankshaft with a crack in it – period.
