I talked to MARINE CRANKSHAFT BALANCING (recommended by Jim Comstock) a month ago. Crank balancing for a Norton is $180. I guessed at shipping at $50 each way. Figure approx $300 to get the job done. Seems reasonable. I am guessing that Norton maybe checked every 100th crank for balance so you get something close and rely on the isolastics to take up any variation on the balance. If you pay the money to get it dead on you should have a motor that shakes a lot less. This would pay even better dividends with a solid mounted motor. For instance...My Atlas was completely stock and the handlebars buzzed unbearably. I balanced it and it made a world of difference.
