Spent some time today removing the secondary throttle body butterflies...as I want to see if it makes a difference to the snatchy throttle issue.

I noticed that the inlets seem quite fouled below where the secondary butterflies are, more so the rear cylinder. Is this normal/abnormal? Should I start looking for some other issue or simply clean them?

As you have probably noticed I have no bloody idea what I am doing😂
Bike is running well, no real issues, so I am not sure what to make of it. Any advice or guidance would be great
