Just got home after a pretty disappointing day of riding Started straight away as soon as I left this morning. I went a different way to work, after scouting last night, trying to find a route with less traffic. My shifting was sloppy, throttle control jerky and braking rough. I thought it was just morning jitters, but my lunch ride and afternoon were even worse. My balance was severely off, I was putting my foot down a lot more than usual, even put my right foot down 2-3 times 90 degree corners like at lights were shaky. To top it off, bike was playing up more than before, idling after riding was choppy and it sounded like it was running very rich. Easing off throttle in second resulted in small backfiring, and it cut out at the lights twice. Shifted to first, raised revs to take off and it just choked and died, it was not a stall, clutch was completely in. Not to mention, in traffic I couldn't relax my arms like usual. Hands, wrists and arms were getting a work out. I usually pay close attention to my form and remember to keep my arms limp and relaxed and keep my thighs in, but in slow traffic then just kept tensing. Infuriating. Confidence was shot and as such I couldn't read traffic like I can most days. Felt like a newbie on the road, not someone who's been dealing with heavy traffic for nearly 8 years. Sad day I hope it doesn't continue.. Sorry for wall of text. Edit: Oh, I also fcuked up pretty bad and clipped someones side view mirror with mine. Wasn't enough to damage or anything, but an audible tap. I stopped and raised my visor and apologies to the driver, they laughed and said it was fine. But I felt so stupid afterwards.
