I took mt M90 case in to a local shop for polishing, and I covered the rotors very well. What I didn't do is cover the gear side of the rotor pack. So, the polishing guy was not careful at all and my rotor pack came back with polishing compound all but seizing the rotors. Not good.
I sent the rotor pack, and case to Logan for him to fix it up. PTFE seals, etc.
I rebuilt the snout myself, and have not re-installed the snout to the case. Im just waiting on warmer weather to install the M90 and spin it up.
First thing you will notice is the silencer holes are filled. Logan assured me he has never had an issue, as he is very careful to prep the surfaces first to make sure that it will not come apart.
Once the warmer weather hits, I'll post a review. I'll first install with the factory sized pulley, then a 2.8" pulley. Here's a few pics of Logan's handiwork. Definitely some labor went in to this.
Dono, take a read on this thread and contact Logan to get your rotors fixed.
