Well, my whining output shaft noise had been getting worse, so I took the bike to the garage to get an idea of the cost. They did what I’d been too lazy to do, stripped the back wheel and sprocket cover. After removing the front sprocket, it was clear the sprocket had worn one side quite a bit, hadn’t been aligned properly. It was also quite worn, I didnt even think to check this as the chain and sprockets had only done about 5k km on it. Obv crappy material. Thankfully, the output shaft spun freely with no clicking, phew! That was great to see. Turns out the rear wheel bearing was the main culprit, followed by the front sprocket, which explains why I thought the noise was coming from the front. I’m honestly so relieved to be wrong, a wheel bearing, chain, and sprocket are a lot better than having to pull the engine and split the gearbox casing. Hate to think what that would’ve cost! It’s booked in for Monday for some much needed love and care, something I embarrassingly haven’t given it for a while.
