My bike is making a tapping noise, I'm thinking its the bottom end going, going to rebuild it soon but just need to get few more weeks out of it.
Any ideas which bearings are making the noise?
What makes you think it's the bottom end.
Sounds like the Ignition Coil firing to me.
Always Originate, Never Pirate!
@Calum bike bike had a piston split in half from running lean due to exhaust leak, thinking the bottom bearings might of been effected.
Well you should have checked the bearings at the same time.
For up or down play.
