Hi Brian, thanks for watching and getting in touch. The 16" tyres are still available from a few companies. Bridgestone have had a tyre for this bike in its legendary BT45 series for ever. These have been superseded by the new BT46, so even today you can buy new and improved tyres for the GPZ. If you ever get one as a project bike, consider popping into our Facebook community for assistance and moral support. Check out my videos, I did an "advert " for the group a while back 👍🏻

Hi, did you do anything prior to this problem arising? Was it always like this or has it "just happened" actually sounds like a connection problem with the ignition and lighting loom plugs under the front cowling. That's only what it sounds like, could of course be somewhere else, but we need to start taking things out of the equation.
