I made a reed adapter due to the Cr 85 vforce 4 only flows a 32mm Carburator And to utilise a 34-38mm Carb you need a bigger reedcage and to acomidate that without porting the case you need a spacer.

This is meant to be 3d Printed

I would recomend atleast Pet G but other plastics would work great aswell Use it with studs to make sure that you dont strip the threads in the case when tightening
