Cheers for the comments, I am sure this is a 99 bike as it is a reddish orange and silver. I picked it up this morning. Not in bad nick at all. A few jobs to do, the usual things, a wheel bearing or two, brake pads and new grips etc, but the engine sounds sweet as a nut. Started second kick without any problems. Owner told me it was fully rebuilt and has only done about 12 hours since. I have no reason to doubt that as it sounds so good. The bodywork is in reasonable condition, if I were doing a full restoration type rebuild I would replace it, but as it is for my lad to learn on, I can't see the point.
So thanks again for the advice, I am sure we will have some fun on it
