Hi anyone happen to have a clear image of the carb drain screws supposedly access through the little pull out plastic tab on side of fairing starting left believe I can see a Gold straight head of a screw head but not getting a bite properly with my 30 mm screwdriver which I grinded bit of also as very hard to get a small head long screwdriver?

Also what are the chances of me getting away with it starting as it been 18 mnts probably since run tank emptied about a year ago?

You will never know until you try. I'd suggest draining the old gas from the tank and replacing it with new gas. Then fire it up.
 
did you run it dry 18 months ago? I'm guessing no because you're asking about drain screws.

FWIW, I bought a bike that someone let sit for about a year, maybe a little longer, and the carbs had issues. So at 18 months its a crapshoot.
 
Warning - those drain screws are made of cheese - if they have never been opened you will probably strip the heads before you can get them open. ;)
If it has sat for 18 months with gas in the carbs, high chance the idle speed jets are clogged - required pulling the carbs anyway.

Can't Remember what I had for Dinner last night let alone did they Run dry back spline ran dry lack of moly unfortunately didn't know about checking greesing when I changed oil/filter & final drive oil same time first shaft owned! any pics anywhere?
 
the service manual recommends a 14" long screwdriver for accessing the drain screws. At 300mm (which is what I assume you meant by 30mm??) you're a bit short.

What most of us find after owning these things for a while, its often easier to just start ripping bodywork off the bike to get better access to things. It looks like a lot of work at first, but after you do it a few times it becomes fairly simple and quick.
