UPDATED DESCRIPTION INFO
Last night I remembered these are not be Barnett friction discs, they are EBC. Also discovered that there actually is a full set, 8, not 7. I liked the EBC much better than the Barnett. The Barnett clutch lasted less than the OEM clutch. Granted, I was drag racing on it. The EBC clutch was much tougher and I only took it out and returned the bike to stock frictions and springs because I was not drag racing the 919 anymore and now I am selling it as close to stock as I can get it.
Honda 919 service manual spec for service limit on clutch discs is 2.6mm
I have put a mic to these discs and they measure as follows:
1. 2.78mm (this is the back one that goes against the flywheel around the judder spring)
2. 2.88 inner
3. 2.80 inner
1. 2.92 (this is the back one that goes against the flywheel around the judder spring)
All of these discs are serviceable. The springs are Barnett for sure and they measure at about 50mm... so they are serviceable as well.
$15 for the springs and discs are free. A steal really considering the EBC & OEM discs are still good.
