This weekend I aim to fix (yet again!) a vacuum leak in the rubber connectors that attach the TBs to the head on my 1985 K100RS. Some say install the connectors dry/ others suggest something like Permatex blue (?). Well, if I go with a gasket maker material, I'll be sure to use a high temp/ gasoline resistant one. The bolts that fix the rubber connector to the head are to be torqued to 4 ft/lbs.? That seems very light. Your ideas/opinions please.
TIA
