I live in a shithole so theres only one store 30km away from me that I can get parts and accessories for my bike from. Anyone ever heard of this brand? I paid 25 quid for this rear tube so it is pretty pricey, dont know if its a good brand or just the store overpricing it?

My buddy and I were testing out the bike after it got gaskets done and got it reshimmed, 2nd ride on it and i felt when at constant throttle it sounds a little off? Dunno how to explain it, crispy? I got my buddy to hop on and let me record. Also the bike does cut out sometimes, but that could be because i give it too much gas at once.. (2011 CRF250R EFI)

In simple terms: am i being paranoid or does that sound like a healthy 250 4 stroke
