    So the longer hose (6) just loops from 1 boot to the next? ..... just by your pic it looks like they go "somewhere' ? :lolsign:

    get some really large heatshrink tubing to redo the carb boots - you'll get it at either electrical wholesalers or perhaps somewhere that deals with large auto electrics such as battery sellers - the big stuff is glue lined and will reseal those boots just fine
    you may even have some luck at a hobby store as this stuff is also used to give lipo batteries some impact resistance

    peace out

    Heatshrink is amazing stuff. I used to use it to make fire juggling gear more "grippy" back in my misspent youth.

    So looking over the cabies againand noticed this the caps on 1 and 2 are on wrong and no oring on wat ever that holes do im assuming that feeds fuel to the needle? By the looks of the diaphrams the carbies have been rebuilt at some point not long before i purchased the bike years ago. (I've only done just under 3000kms on the bike)

    OMG!!!!
    That is the vacuum feed from the carb throat. It is where the vacuum comes from to lift the slides.
    There are also supposed to be o-rings in there and of course the caps are on backwards..

    So that could be all my issue is. Some people shouldnt be allowed to touch carbies -.- I've got a temp oring in 3 and 4 until i can afford to get genuines. I would've thought that should played havoc on everything not just top end

    You have probably been riding a 2 cylinder Zeal for a long time. This will be interesting.
    You should be able to get yourself some close to size o-rings at the local bearing shop.
