OK I know what yics is, what is does, ECT.
There is no port to use to block off the system to sync. the carb's on the 400 twin dohc w/yics.
I noticed with the vac. gauges connected that the gauge readings on decel would get stable enough to get a reading and would change with adjustments, So I got them as close as I could during decel and tweeked a little more by ear/and exaust temp.
I'm close runs pretty smooth, pulls good, idle to 6000rpm, but I get some stumble/cough/spit, slight not bad,on tip in/accel above 6250rpm.
My ? is. Does anyone know the factory proceedure for sync. on this model?
Or your own personal trick?
Or do you think I have another issue?
Thanks in advance for any info.......DW
