I warm up my motorcycle in the yard before I ride out. However, when I shift into first gear, the bike jerks forward and sometimes stalls. The clutch stops working and the shift pad doesn't move, so I can't shift into neutral. All these problems go away if I press the clutch and roll the bike back and forth a few times. After that it starts working normally. This only happens when the motorcycle is started for the first time during the day. I have read that this may be due to the clutch discs sticking. It's not critical, but it's still annoying
Please advise how to solve this problem
P.S. Motorcycle - MUSSTANG FOSTI 150. I'm a dumb newbie, I've only been riding a motorcycle for a couple of weeks
