I had this fault on a Kawasaki 300b, however it was not running well. It turned out to be a soft camshaft. Because the lobe was getting smaller it didn’t open the exhaust valve enough to expel all the gasses, and things just got hotter round the port. The valve clearance hadn’t grown as it was the cam rather than the follower that had worn, and it was still “standard” at the part you measure clearances.
