Dear sifu. Wanna ask y my bt20v 's exhaust once in rainy days it'll started to sound "bok bok bok" a bit like misfiring/backfire but instead it wasn't. Why le? Once I depressed the clutch the sound gone n when I continue to floor the pedal the sound again bok bok bok. It usually happened in heavy rain. Anyone experience it b4??? Sound vy annoying. Pls help...
