Whenever i give throttle there is a noise.

whenever i give throttle for any reason that puts much tension on the engine, there is a loud rasping exhaust note, very loud, and roary. the bike is a 50cc 2stroke ludix blaster. this is worse when attempting to maintain speed uphill, the bike is not de restricted and is not modified (worth more like this and no point making a ped go faster) the prequel to this occurence was a loud click from my engine followed by it going dead, it started up fine and rode ok for a bit, now, it rasps, any ideas?

Could be the reeds...but I think they last a bloody long time so is unlikely.

A leak in the exhaust or air intake somewhere?

yes but before it started. a while ago as i was riding uphill, there was a very loud click, and the bike went dead, never used 2 be raspy before this, and there are no holes in my exhAust
