I know I've asked questions about crankshaft balancing in the past, but now that I've ordered a knew crank for my engine, I plan on actually attempting to make it balanced. I've looked through this forum, and the information on balancing is quite vague. There are no visual instructions or really instructions at all for how to do it with our china girls. In fact, I'm not entirely sure anyone in this community has actually done it. Here's a quote I found in a thread about balancing a 2-stroke engine: http://www.radiocontrolzone.com/archive/index.php/t-182527.html Is there any validity to this? Does this mean that I can't balance my crankshaft for less vibration? Also, I keep reading on the internet about weights, counter weighs, etc. Where on these crankshafts would one add weight? Does one simply drill out material in the right places to transfer weight?
