Thanks for the insight, I may have worded it incorrectly on my part, after reading it back over. I’m used to the general hissing, but this was much louder than usual, as if I it had built up a lot of pressure. I’ve ridden it since this post and didn’t have any bogging issues, and venting seems back to normal so may have just been a one off, if it reoccurs I’ll start the trial and error process!The fuel cap hissing or singing is completely normal and not a fault. The hesitation will take trial and error to diagnose,it could be fuel,mechanical or electrical. Start with one thing at a time. Some things to get the ball rolling.
Plugs.
Coil sticks.
Bad fuel.
