Is it the NUT holding the handle bars?Y'day I spent the whole day at workshop; SHIMs didn't have any issues, valve clearance was only 0.24mm of difference (was the highest among the 4). Oil filter was right in position, which means, the vehicle didn't deprive of oil circulation. But in the afternoon, we found the alarming issue that caused the vehicle to this stage. We never expected such a thing to happen!!!
