Ive just bought a rvf 400, and it soungd a bit tappy from the rear cylinders, is this normal, do I need to get the valve clearance checked or something else. Cheers in advance Paul

might be the rear pipes - they can create a tap tap noise if slightly loose - nip them up and see how you go

Spot on! I tightened them up this morning and she runs so much smoother thanks alot
