after carb clean balance all cyclinders are hot now for the rest of the bike

[His Dudeness]

right the top of cylinder 3-4 are hotter now defintatley but they still dont seam to be as hot as the other two..... i will put balance on them later and see whats going on...... if the balance is out will it give  a diferent tempreture reading??

It can do. But how is the bike running is the important question I don't think you mentioned that. What is it doing? Is it lumpy at idle? Is it mis firing when you open the throttle? Does it feel down on power when you're riding? If you've got a mis or a cylinder that isn't contributing you can use the water on the exhaust trick to show which cylinder is the problem cylinder. If the bike is running ok and there's no mis and there's still a difference in exhaust temperatures it can be caused by a rich or lean mixture. The leaner the mixture is the hotter it burns and the richer the mixture is the cooler it burns so if you do the water on the exhaust trick and it can give you an indication of rich vs lean on each cylinder, also if you take out the spark plugs and read them. Black and sooty is rich, white is lean, wet is no spark, and you combine that with the exhaust temp you can get an idea of the problem.
