Not sure how many of you on here have had experience with mopeds. Basically I have wondered for a while why there was a small bolt in the small section from the engine to the silencer on my moped. I thought I would remove it today and it sounds much improved. Very throaty. With it in the bike sounds like a whining mini engine (which is good if you like it quiet) It sounds really sporty with the screw removed, almost like a motocross bike. Power seems to be the same, only difference is I think it takes an extra crank to turn over. Are these made to be removed to enhance the sound or improve performance? All it is basically doing is creating another outlet for the air. Just lets out the exhaust gasses before it reaches the silencer. So I am not sure if this is made to make it sound sporty or are they not built to be removed? Any advice would be much appreciated. It sounds like a 250 not a 50. :D Make people turn round to wonder what it is instead of laughing
But if it will cause any damage to the engine then it will be going back in.
