Items in a gasket set

[Guest]

Me again,
I purchased an OEM gasket set for my bike, inside there's a small bag with couple of o-rings, strange copper washers(they have a tab) and two larger metal rings.
Can anybody explain what are all these parts for?

Either intake o rings if they are big or oil pump orings if they are small.
Washers are for under head nuts because they get gouged when you torque the head

Large metal rings -Exhaust gaskets.

Large metal rings are exhaust gaskets. Strange copper washers are for the head bolts with oil passages to seal them - probably the outer two on each side

Thanks Guys, there are quit few o-rings, some big and one or two tiny.
I'll try to upload a picture later

There'll likely be an O ring for the gear position indicator as well.

There should be two large O rings for around the base of the cylinders too.

Was the set for the 400? If you have a set for the 450 there are things that will and will not work.

I didnt catch the tiny o-rings but it's there, also what are the metal washers for?

Got a pic of the head gasket?

Metal crush gaskets are for oil holes in the head gasket around the outer studs.
Metal washers are for under thw head nuts.

I see an oil filter O ring there too.

I see the cam chain tensioner gasket, there are some small o-rings in the tensioner, probably what you see.
