This particular bike has always had a noisy primary. The bikes done 10,000 miles, and was happy enough rattling along at that. But it clearly needed checking out.
Backlash gear incorrectly sub-assembled with spring dowl pin fitted backwards, and incorrectly positioned, so it wasn’t even acting against the spring 🤦🏻♂️
All sorted….this bike has never sounded so quiet. I’ve also used him as a guinea pig, trying out some Motul 300v 15w50 in his primary side.
