Hi Ronnie
i know this sounds cheap n cheerful but the part you need to replace is probably sourced from a suzuki main dealer, they,ll have details of part number on microfische thingy, or if you still have the tube bit thats snapped off try using araldite or similar, as long as its air tight it should be ok as its just for a vaccumn hose.
reason i say araldite is i had a crash in a race & caused damage to same part as you have, to get out in next race it was glued back on
hope that helps.
cheers
andy
