Magdyno fibre drive gear - noisy?
« on: 26 August, 2017, 12:19:03 »
Both my B31 and Ariel single suffer from what I think is excessive mechanical valve gear type noise (what do you mean, I shouldn't have old bikes then?  ;) ) that I'm pretty sure is due to the backlash between the dynamo gear and the fibre gear. I've narrowed it down to that area - it's more distinct on the B31 than the Ariel - with the trusty stethoscope. Before I stump up the brass on ordering new gears, has anyone replaced them and noticed a distinct improvement?
I know that noises can be notoriously difficult to track down but pretty much everything else has been addressed now.
