I'm rebuilding the above motor and noticed in 1994 Yamaha increased the amount of oil injected at WOT to 50:1 from 80:1. Is it possibly to change the ratio from my oil injection system at WOT to reflect the changes Yamaha made in '94?.

I wouldn't change it, MMD5.<br /><br />Yamaha had their reasons, and they probably included changes in detail in the '94 engines.
