No tight valves, checked them and only one in front cylinder was a bit tight but still within range.
While riding occasionally it feels a bit of a fart into the airbox, especially at low revs. Spark plugs are ok with good color. Thinking about injector operation... related to random incorrect spray time, a fraction of a second off the valve opening time, perhaps...
