Re: yes, yet another stuck fuel cap

So I’m persevering with the rope trick as well as soaking the lock with plus gas penetrating fluid. I am pulling really hard but it’s not budging.

The outer plastic ring covers it. Mine has been modded accordingly for ...

Re: Unexplained noise - sounds like a bearing - R100 Mono Shock 1991

Unsure how the sidecar would affect this diagnosis method, but rolling the bike on a flat surface should not illicit any clicking sound from the trans. If you hear it, suspect that big front bearing.
