Bonneville America Forums Forums Technical Forums General Tech what is the whirling noise in the motor??

Hey guys I was wondering If anyone has pin pointed the sewing machine noise from our bikes, Mine doesn't make much of a tap but more of a whirling type noise like a sewing machine when I am riding.. I was thinking it probably is the cam chain cause u can vary the noise by playing with the throttle.. any way I need to lessen the noise because its geting to the point where i can't stand riding the bike cause the noise is so annoying, it makes it feel cheap.. well thnks for any advice

It's the cam chain... normal for many british engine designs (you should hear what straight-cut drop gears sound like in a classic mini engine!). If you can hear the chain, your pipes aren't loud enough.

Ear Plugs

You'll be amazed at how many odd noises disappear when you add pipes.....
