Silver century crank against a 40+ crank

Post by Merry » Wed May 18, 2016 11:02 pm

So I acquired a fairly nice silver century a while ago and quickly realised someone had had a go at getting the flywheel off which meant the crank was flattened at the end and even slightly bent, did what I could but decided it was time for a new crank in there so I got one ordered
And soon stripped down the crank case,
I then thought I'd strip down a spare crank case from a 40 featherweight I've got laying around to compare.

Long story short before I knew it I had swapped the big rod and piston over to the lighter crank because I'm too impatient to wait for the new correct crank to arrive.

Think the counterweights are too light? Comparing them I think the silver century counterweights look massively over weight for the weight of the piston.. But I'm not an expert.....

..... Thoughts?
