Its not the pump, its the air. Old factory air was pumped in when the bike was made and didn't get out until the tube punctured or the tyre was replaced. That's when new air got in and that's when the problem started. A new tube will of course have new air in it.
Its a bit like Lucas smoke, once it gets out the electrics stop working. You can still buy genuine Lucas replacement smoke, but as far as I know, you cant get authentic BSA, Triumph or Norton air.
Thank you for your support...
