whats wrong with my dt125x?

if its got a dep pipe you cannot take the baffle out unless you drill out the rivets,using caustic soda is an option as peesian says but caustic soda is very corrosive and will mark and damage anything it touches including you,also its not that effective.the best thing to di is have it cut open and the blocked areas removed alltogether and then welded backup again.

remove your exhaust and fill with caustic soda overnight to decoke and remove baffle first to wire brush

its just burnt/unburnt oil dont worry about it ,if you rode it hard all the time you probably wouldnt see it but its basically a build up of mixed burnt and unburnt oil in the exhaust and when you really ride it hard it will blow it out through any gaps and also the tail pipe.
