sailor Posted February 25, 2016 Report Share Posted February 25, 2016 Most (if not all) Trial moto bikes have a specific sound. It is a chirping, howling sound. Here is a sample (from 5:22 to 5:27): https://youtu.be/T4HB6rxpjRQ?t=5m22s I am wondering about the exact source of this howling sound. My assumption is the generator, but I am not sure. Any advices are welcome. Thanks Sailor Quote Link to comment Share on other sites More sharing options...

dadof2 Posted February 25, 2016 Report Share Posted February 25, 2016 As above due to straight cut or near straight cut gears and float on the clutch basket. Quote Link to comment Share on other sites More sharing options...
jonnyc21 Posted February 25, 2016 Report Share Posted February 25, 2016 Sure sounds like the strait cut gears to me. Quote Link to comment Share on other sites More sharing options...
