Beatrix - 2020 BMW R1250R Exclusive in Pollux Metallic Matte
Interesting. My "2 cents": spring rubbing might create small debris after prolonged use, and increase stress on the spring attachment points (are these metal?). If there is no cover above the spring, small derbies shouldn't be an issue, otherwise shavings might clog something in the mechanism. You might want to add a dab of plastics safe grease (silicone based?) to the bottom of the spring to aid in sliding on top of the pulley. Again, grease is probably not necessary due to most plastics self lubricating properties.
