E-Bay Item number: 190115059823 This is the type of bike at the type of price I like. I am always sceptical of "simple repairs" though. If that simple I would think the seller would do them and maximise the asking price. I do not know anything about this lump, but I think there is a difference between a rattle from the top end and a tappet noise. What else can cause a rattle, I am thinking cam chain, knackered bores/pistons, camshaft. Sod it, I have put myself right off!! Bill
