I have a '79 GS 550L that I'm fixing up. Got it running better than when I bought it but at about 60% throttle it flattens out and dies back down. I'm going to check for a vacuum leak today but I'm thinking I need bigger jets to go with the new pod filters I put on. My carbs are Mikuni Kogyos ...
Did you notice your neighbors having an increased number of seisures around Christmas time?
