[QUOTE="Patent1, post: 1438648, member: 962"] Attempting a throttle body sync on a 2005 Gen I. Turns out cylnders 1-3 are pretty close, but cylinder 4 is pulling much less vacuum, and its air adjustment screw is bottomed. I see two alternatives: A. Use cylinder 4 as my reference cylinder, and sync cylinders 1-3 off cylinder 4, or B. Adjust cylinder 4's mechanical linkage adjustment screw to hopefully increase its vacuum, and sync the cylinders using cylinder 3 as my reference, as Mother Yamaha intended. Leaning to Option B. Do you folks agree? Any other suggestions? [/QUOTE]
