Valve springs

I have a stock of valve springs for the 398cc motorcycle. As suggested by the late Bob Thomas, these are 10% stronger then standard and were made by Terry's some years ago. They work out at £20 per set of four including postage and packing.

It's easy to make valvesprings but you have to bake them for an hour at 200 degrees celcius after making them.
