lcrken Posted September 11, 2015 Share Posted September 11, 2015 I've recently come accross a tuning sheet for the 1986 VF500 carburetor calibration kit from Factory Performance. In it they mention "Factory Ignition Advance Modification suggested. Does anybody have any idea what that modification was? No mention of it on Factory Performance's current web site.

Member Contributer DannoXYZ Posted January 27, 2023 Member Contributer Share Posted January 27, 2023 Just came across this unanswered in search.... Easy way is to install starter-clutch from '84-85 VF500F. The trigger bumps are advanced about 5-degrees more than '86, so you'll get some quicker response out of it.
