hey guys i ride a honda cbf250. was going to work today and started noticing a crckle/ticking sound when dropping the speed from 60 downwards. not even changing gears. just slowly closing the throttle. stopped to check if the chain and sprocket didn't catch something. couldn't really se or identify if it was actually coming from there or the engine itself. bike is still under warranty but i thought i'd ask your opinions,since i'm not gonna get it looked at just now. should i kep riding or is it something to be aware of??? any thought appreciated. cheers.
