mine cost me 900 but with standard rods, and a very good deal on my clutch the most expensive parts were the pistons, if ur not going for big big power i personally never balance anything apart from the pistons which came balanced for free, as these engines are very well balanced as they are, so i dont see the need unless want a big big power, as if u put one crank flywheen on machine and balance it then swap it to another it will most likely show it needs a balance again, basically saying its not just the person who does the job but when did the machine last get calibrated and if so could the person be bothered to do it right, if anything like our brake rolling road they dont, but just charge u for it and make out there doing something, which can do more harm then good as there very well balanced as they are from the factory, oviously though if u change the flywheel then get it done.
