The bike is starting and running reasonably well but I’m aware that it’s a good few years since I last stripped, cleaned and balanced the carbs so I’m going to pull them apart over the next few days - externally they are filthy but as I say they work well enough. Obviously, the float bowl gaskets need changing - has anyone used the Silikone alternatives supplied by Siebenrock as the cork one’s last next to no time. Any other recommendations?
