i took fuel line, drilled some small holes in the caps of the the bottles, then coated the hoses in permatex gasket maker, slid the hoses in the holes (had to heat the hole a bit to get the tubing in) then permatex it again, while that dried i built the holder... this will work great for when i tune the carbs and set the points... holds the bottles up and out of the way so if they do fall you will not get gas all over the bike. ill get a close up tonight before i head to the shop
