Hi again to all I'm trying to get a 92 Gsxr 400 started I've tried everything I can think of, first bike would start and drive but dirty , then started it one day wouldn't idle only stay running at high revs with a massive flat spot -bogging standing still, so took off carbs took apart ultra sonic cleaned them , and got a complete carb rebuild kit all the seals and piolet washers,it had adjustable needles and 100 mains , screws 1.5 turns out . Got it running again but would never idle and would have to use a lot of choke, so after about five times taking them apart and cleaning giving them the airline setting floats, I put 115 mains raised the needles 1 notch and turned the screws out 2.5 turns because of a stubby can aswell thought still might be starving , now only runs on full choke when starter is engaged leave off started and cuts out and won't take any throttle this thing is killing me ! Took lots of carbs apart and put them together again but this one has me melted , pls pls pls any help il be grateful as this is going on weeks now thank you , what am I doin wrong
