Let me just say, once I was on my way, I held on tightly, white knuckled the hand grips and anticipated my rear wheel flying off, the entire journey. I actually left out my ear plugs in anticipation of hearing the impending doom.
Luckily, I arrived home from my jaunt intact, lug nuts correctly torqued, but with the realization that the fearless confidence of my youth was long gone.
Linda, your confidence will return after you accumulate additional successful service jobs. As an RN, you first patient injection was likely very upsetting, yet I bet you don't give it a 2nd thought now. Rechecking the order of operations and torque values will make each service job incrementally easier.
I just took my rear wheel off today. It wasn't for a tire change, it was to remove the Ohlins shock so I could overfill the preload oil. Pics, details and a post to follow tomorrow. Anyway, when I rode the bike afterward, I had ZERO fears about my work, because I actually did retrace the order of operations to confirm there were no skipped or partial service operations. That's when I realized I had not yet pumped the rear brake pedal to push the pads to their working positions. Even after my 2nd "mistake" - - - trying to start the engine while it was still in 1st gear (to loosen/tighten the lug bolts), I was not the least bit insecure about the other work completed.
Maybe it's just a guy thing.
