akbek, well, so at the end of a long trial and error you seem to agree that 26 are a better fit for a street 500? I believe some of us told you this already in the first page of the thread 
some throttles have progressive ramps that open slides slower at the beginning, a relatively easy to try mod that might help with bogging.
When I bought my bike it already had the CR29s but I do agree the CR26s are better for the street.
Are there any posts on this mod?
