Hi there I'm new to this site and to the yzf750, I have just got myself a yzf750 that I bought from an auction. I'm trying to find out how i go about cleaning and balancing the carbs, as it only seems to be running on three cylinders. So I'm gonna put new plugs in it and i wanna balance the carbs but I'm not sure how to do it! So any help would be greatly appreciated. Many thanks
