usually backfire happens when it runs lean , your not getting the fuel through the carb. your float bowl may just be stuck.

I was getting same thing with my demon 625 carb and when I took the bowls
off the floats were not even in the housing so I was getting way too much gas.

I put the floats back in and now runs fine
