I'm not familiar with that engine specifically, however in my experience those plastic ones are usually to prevent marking the painted surface under the screw. Since the sealing washer will do the same thing, I would imagine that should be good enough and you can omit the plastic ones
help with valve cover screws
I ordered stainless steel valve cover bolts for my GSXR 1100 engine in the UK.

plastic washers were supplied to the screws

They aren't sealing washers, are they?
The sealing washers are thinner than the original sealing washers and are not flexible.

or do both panes have to be mounted? First the plastic washer and then the sealing washer ???
There was no instruction included.
Or do you just leave out the plastic washer and just mount the sealing ring, as it is the original?
Who can please help me with the correct answer?
Thanks in advance, Andy

Have these screws also.Had to use plastic washer/spacer on mine as the shoulders on the bolts were bigger than stock bolts.Standard seal could not be fitted only as bolts would leak Have attached pics for reference. 1st pic no washer.2nd pic stock seal .3rd pic plastic spacer and seal.

So the difference that Suban12 has with the screws is not what I have.

The left stainless steel screw has a collar height of 5.2 mm. The original screw on the right is 5.4 mm high at the collar. So that's not what the plastic panes were intended for.

I would bet Suban's screws were for something else originally - note the radius cut after the threads end. They wouldn't bother with another set of operations for no reason, those were intended for more load than squdging a valve cover between a gasket and a rubber seal.
Just my take, I'm not an aircooled Suzi guy so maybe these things break on the reg and it makes total sense
