So I have been driving the Strat for about 6 months now and always when I would shift from 1st to 2nd I would get a backfire. While doing more cleaning on the bike and looking for the transfer case drain I know noticed a bolt missing from the muffler to the Y of the exhaust 2 into 1 pipe. Guess what no more backfire. does it mean better gas milage?

Don't get your hopes built up but maybe.With the leak right by the o2 sensor it may have f%#$ed with readings.
