Did you have the idle air adjustment screws out when you did the cleaning ?
If not, you probably did not get the low speed jets clean.
They are very small and not removable and easy to miss.
Are you testing with a stock air filter in place ?
It is amazing what a huge difference there is without an air filter.
And finally, while SeaFoam is OK for routine maintenance, it is NOT a really good cleaner.
Gumout and Berryman's B12 Chemtool are much better.
P.S. Higher octane does not equal better gas. Your bike might even run better with regular.
