Hi all just bought a 2011 Triumph Bonneville SE. When out riding and decelerating the exhaust pops and bangs is this normal, its all stock as far as i can see Cheers all.
If the pipes are stock then I'd guess the carbs need to be re-jetted. The condition you describe makes me think the engine is running lean.
A leak on the exhaust system before the silencer(s) can also cause this. Check for loose exhaust fittings/clamps etc.
