I`m glad to see you have "upgraded your spine" 
Hopefully this will allow hours on end of enjoyment in the saddle without pain...
This is my prayer...
When mine started giving me problems as I increased throttle, it was because the diaphrams in the carb were worn and had holes in them, which allowed air to enter the closed system...
Hopefully your cure is less expensive than $110+ each for the diaphrams as mine cost this much...
However, the Honda Buck$ spent made it so I can enjoy my ACE
Good Luck,
Dennis
