I have a 1986 VF500 which runs well apart from there is a rattle coming from the engine which i cant find. This however does not affect performance, so has got to be something simple. The bike has just had new fork seals but needs new battery. It has 41000 miles on the clock and currently has no tax or M.O.T. Any questions please e-mail me and i will be happy to answer. Alternativly you can call me on 07957701073 .
