Motorized Bicycle Crank Balancing Made Easy! (CHEAT SHEET WEIGHTS)

Seems many want to make a balanced crank! Sure you see most people Just drill 3 holes in one and call it a day on YouTube! So how do you know what they show you is real or is it just a bunch of bs? Well it is kind of a little of both!

Typical crank is only balanced 60 - 70% Most 66/80cc kits are 65% or lower!
For an example Stihl chain saws will have a very well made crank with balance factor of about 75% to 80%. Or you can by the Walmart special chain saw which has one of 65% normally in that area! Bare bones min required to run. buy making the balance factor 70+% you increase bearing life! Reduce vibration! Increase piston and ring life from lack of deflection as a result! smooth running beast of a engine!

I had many questions of how in the hell did I make that crank and how I get the number to balance one! So here you go! a detailed video on what you need to know and do to balance a crank! How much to drill! and how much weight is removed as a result!

If your building a Minarelli, Ms380, Ms460 Ms660 a balanced crank is a must of your case bearings will be dust in a short time frame!
