Yamaha banshee piston clack

[Mayanbanshee]

I have a Yamaha banshee and you can hear the pistons click clack. I was wondering if that was bad and how can I fix it?

Sounds like piston slap do a compression test . if low need a rebuild of your top end and make sure the noise is comin from the pistons and not the rod or crank bearings .
