Someone with YS or someone that really knows what they are doing needs to make a video of a YS engine tune and post it here. Have the engine out of tune due to different reasons, then show it being tuned. I would like to see it done for a 1.10 since most of the post are issues with it. There are a few videos on you tube, but the engines are in tune to start with. It would really help to see and hear how to tune these wonderfull pain in the butt engines.
