Well i am doing a rebuild on a motor that was frakinsteined i needed new rotors so i got S5 N/a rotors but it had 12a rotors and e-shaft and flywheel and housings. what do i need to do the build.

I have s5 Irons/housings
S5 rotors
can i use an s4 eccentric shaft flywheel and counterweight or do i need S5?

Thanks in advance

 

im pretty sure the e-shaft doesnt matter but the flywheel and counterweights will need to match your rotors.

 

eshaft is the same from 86-91...

you need to use the balance weights for the rotors you are using. ie if you use s4 rotors, you need s4 weights. s5 rotors take s5 weights, etc etc

if you want to do something else, it must be balanced
