Numbers are numbers and just what is on the paper that crank is junk. Stop this video at the end and compare the numbers. The crank my son spun was a external balanced crank. It is now internal balanced. 1.36 grams and 0.21 grams, He screwed that crank up bad. He should be liable
from what I see . He has it at 138 grams and 186 grams. Comparing the two It is 138 minus 1.36 is 136.74 grams out of balance on one side. 3 grams and less is good. 136.74 Not good at all. He forgot to look at the decimal point there is none.
A woman would love to sit in the seat and rev that thing. That's better then a sex toy.
