if its bogging and back firing, that's telling me that your not getting enough fuel. Might even be to lean. Try cleaning your tank and petcock, also clean the carb really good. (You might wanna go with the stock set up if it was me). Another thing you can do is check the float and needle. I think the fmf power core is your problem cause most of the time all you need is an aftermarket exhaust and jet kit, with High flow filter.
