there is a noob mistakes thread and perhaps this thread already exists but I thought it could be a place to post the Mistakes you have made as an experienced rider who should have known better! I'll go first Yesterday I took a bike out for a ride, first ride in 8 months after a crash that left me with a spinal injury. I have no feeling in my left foot and limited power around my left ankle. To top it off I also have no spatial awareness of where my left foot and toes are in relation to the rest of my body. I wanted to return to riding without needing to modify the bike to do so e.g. fitting an actuator to change gears with a button on the hand controls. Anyway after a lot of physio and testing my ability to shift gears, i have reached a point where I can safely do it, and here is where my huge mistake begins... I have been tinkering with my shift lever position on my bikes which involve loosening lock nuts and winding the linkage in and out to get the right position and a lot of getting on and off the bike to test the position. Some might guess where this is going. so I am all set to go for a ride just a short one with a few different traffic situations to get my nerve back. i decided a loop around Revesby along henry lawson drive and down the motorway, henry lawson drive has some really nice sweeping bends and is a quiet road. As I am riding my ability to change gears is getting progressively worse and as I can not actually feel the shift lever against my foot when i am shifting I am thinking my ability to move my ankle must be getting worse as the muscles often tense up. the inability to consistently shift gears starts depressing me and the problem is getting worse until I can't shift the bike out of 4th at all. Its at this point I look down to see what my foot is doing only to notice the shift lever is nowhere to be found WTF! for a few seconds I am perplexed and think where the fcuk did it go and how! then it dawns on me... I only tightened the locking nuts with my fingers and in my excitement of preparing for my first ride in a long time forgot to cinch the nuts up to the correct torque. Now WTF do I do! I stay calm because thats the kinda operator I am options.... options.... i'm thinking to myself. I'm in 4th with a hell of a lot of luck I can ride this thing all the way home provided I don't have to stop and even if i do at least the walk home won't be so long. Option 2 I stop now and see if I can fix the problem, but if I stop there really is no way of getting moving again unless I want to ride home in first and again hope I don't have to stop. I decide to stop and attempt to fix the problem but I am certain I won't be able to as I can't see the shift linkage when I look down and without it I am fcuked. I pull over and not a moment to soon... I dismount look down and can see the shift linkage is still hanging on and its an easy fix and i'll be mobile again. I barely touched the linkage as it fell to the gound it was hanging on by less the half a thread! a few more seconds of riding and it would have been lost and my problem much larger. So i get it fixed despite the bikes tool kit having no 10mm spanner despite that being the most commonly sized nut and bolt on a jap bike. The good news is with the things tighten up properly I can now shift easily and consistently I've got my nerve back and I'm itching to do some more riding. Note to self make sure you tighten everything up properly! I SHOULD HAVE KNOWN BETTER!
