Easiest way would be to get a Gunsens carb balancing kit ), they aren't expensive. Get it to a fast idle and you just cover one of the ram pipes and it gives you a vacuum reading from one carb. You then do the same to the other carb. If they are different adjust accordingly.

 

Before I had the gunsens I used a small mirror and a torch to look down one of the carb bodies when the engine was off. Get a mate to open up the throttle and hold it when you have W.O.T. on the carb you are looking at (ie the butterfly will be perfectly horizontal). Then go to the other carb and see how far out it is from W.O.T. and again adjust accordingly.

 

I'm not sure how kosha the second method is as I thought it up myself but it did the job for me

 

Hope this helps,

you can also pull opposing HT leads off while running (with something insulated!) and hear the difference, helps if you have a tight air-box
