Exup valve - fatbloke62 - 18-03-21

The main thing you need to check is concentricity/run-out of the exup valve, as long as the valve itself can freely rotate by hand with said cover on and the 3x allen bolts installed your good to go.

Mine's exactly same, don't worry about it, avoid cheapo copper grease, it's not up to the job , buy proper high temp copper slip.
This stuffs not bad for money.

or you can pay a lot more for higher grade stuff.

The FZR1000 boys now use ceramic grease for lubing, as unlike copper slip it'll withstand the heat (rated for VHTs) and is closer in spec to the stuff yamaha used at the factory.
This sort of stuff:

You can get it cheaper than that, and one tub will last for years.
