With a longer duration, high lift cam, higher compression pistons, porting, etc, the FI (and small carbs in M30 case) had to be ditched. My M10 E21 was putting out about 60% more power than stock, so there was no way for the K-jet to handle such. My M30 was putting out about 40% more than stock, and the triple Webers were super easy to tune (and a bear to synchronize  ). |
I can so much relate to all of this
