sounds similar to what happened to me a months ago after cleaning my bike
inadvertently dislodged the vent hose that connects to the fuel line between the two carbies. when I say dislodge, the hose is meant to be clipped in position where it terminates to atmosphere. mine was sticking out on an angle and during high speed must have been creating a vacuum in it, thus preventing a flow of fuel into the carbies and creating a surging or no response to throttle as you describe
this hose not to confused with the tank vent hose
I would also be making sure the inline filter between the carbs is clear as well
One thing I left off that I also did was cut the fuel vent hose (I think it is called a fuel vent hose) at an angle, that comes out of the bottom of the bike (as forchetto had recommended doing in some thread) I did this also about 2 months ago in response to try and fix the sudden bike dying/stalling. Obviously that wasn’t the problem and it didn’t fix my issue. But now I have this NEW throttle problem so maybe this cutting of the hose has contributed to this new problem?
I only mention this after reading Bonza’s post. I wonder if that has something to do with it?
with all that work you did to the tank, you did check the inline filter didnt you?
