1981 XV750 Ignition timing angles (Old Australia)

Post by fricksj1 » Thu Aug 11, 2022 7:09 am

Hi there,

I have been trying to find some information regarding ignition timing angles and have not been able to find anything in my service manuals. The only information I can find online is from the link below which has some diagrams that appear to be copied from a manual but I cannot see a source, so hoping these are accurate!

I am looking for this information for my 1981 XV750. Does anyone know if the above information is accurate or know of any other sources for this information?

Thank you!

Welcome to the forum!

This is for the 1982 920, but it use the same igniter as the 1981 and 1982 750

Found it online, but likely from the factory service manual.
