Went for a short ride yesterday and noticed a lot of decel popping. Parked her in the garage and started checking the exhaust and sure enough the exhaust on both cylinders was loose. Grabbed the torque wrench and tightened it back up to specs 120"lb. Took it back out, problem solved. I guess the weather change may have had something to do with it getting loose. Question: Anyone else have the same thing happen, how often should one check this. I read in the help section that adding another nut as a lock nut will keep this from occuring. Thanks!!
