I don't understand this comment. What gets trashed and why?
I am familiar with the larger front sprocket allowing the chain to hit the back side of the primary and trans but have not heard of any issues with the inside.

Primary

I figured as much but he said inside primary. That and I don’t understand why an oring chain would cause a clearance issue.

Because that are is part of the inner primary cover I guess...O Ring chains are wider, as well as taller as the witness marks on my inner primary will attest.
