So ever since I bought the bike used (runs great) I have noticed a low rpm type of slapping noise while riding through the parking lots of where i ride and when going slow on some trails. Well come to find out I was missing an exhaust spring along with the O-Rings being clapped AND... the chamber being “pushed” back against the frame (not kinked or smashed) causing a gap at the cylinder where the pipe (FMF gnarly) slides over the exhaust port. At 1st I thought it was “chain slap” but my chain is 3 finger height and in good condition and I keep it lubed.
I plan on buying a new gnarly pipe next week. But let me know what you guys think!
