My bull is a 2011 model std UCE with a short bottle silencer and with 9450km on odo. It's a pleasure to ride it and the beat is very nice as well(not so loud but has enough bass)
But last week noticed something strange with my bull. The beat gets louder(very loud) and the kicker gets hard after a journey of around 100km. But if give a wash after the engine gets cold or after keeping it in garage overnight, everything seems normal.
Recently, when cleaning the air filter myself, the black hose running from air filter box to right side engine case, was found broken at the air filter box end
. Is it something related to the issue? or is it engine over heating due to incorrect carburetor tuning(do we need to tune carburetor after silencer/exhaust change?).
And one more question, what is the small box(switch like black box) under left side of the seat(just above battery compartment), with a cable connected to it?
Sorry for so many questions at once. Waiting for your advise.
