Fund part of my problem being I've lost the valve balance screw and trying to find screw size I being a nightmare I have the rf900 manual same engine except the 900 has hydraulic clutch system at min bike sat in garden as when it start few seconds it floods I'm useless with carbs

If you mean the screw in the middle that balances the carbs in pairs that has to be a standard Metric screw. I've probably got something in my toolbox.

If it's flooding that's not balancing mate. That sounds more like leaking/stuck float, needle or bowl. They need to come off and be serviced I'd suggest.

If fuel is coming out of the cabs the they will need to be took apart and cleaned , will be a stuck needle valve , cant balance them with fuel coming out of them . so have a go its not that bad

thats because they are a mile out of balance . if you take the air box of and lift the sliders you will see the butterfly,s now get them all set by eye , i can get them almost spot on like this then put the vacuum gauge on to set dead right ,
