Good afternoon. I've encountered a problem. After 15-20 minutes of riding, the bike won't shift into neutral. Not from first, nor from second. I feel like in first gear, with the clutch fully depressed, it moves forward slightly. The oil was new and topped up to the correct level. The clutch lever is fine. When the bike stalls, it shifts. Any ideas? It's not the clutch cable. I checked it with the cable fully tightened.
