I got stuck and gave up....had a nice surprise in the post this morning new float needles....they are for the GS550M model Katana...however, they are nothing like what I have on the bike

The hand brake system is off a bandit....

and I discovered this morning the carbs are not the original, they too are off a bandit bike....

How is this possible??

No I dont know what is and what isn't genuine on the bike, should I buy a carb set which is the correct model? My mechanic said to me he thinks the carbs were a bit on the small side and wondered if they were the right ones, but said the bike would run ok....

Now I have full carbs repair kits x4 for the wrong model....
