plastic plugs?

can some one tell me this. why is there plastic plugs under the cylinder assembly (within the cylinder assembly itself)?

are they needed or not?

thanks

Not sure but I think they dampen vibration

If I recall correctly I think the part you are referring to is there to reduce wind noise. Without them, at speed, the wind tends to howl through the fins.

I actually think they're there to dampen vibration between the fins and to prevent their cracking.

i always thought it was kawasakis way of being nice and making it easier to relocate studs,another theory blown to he!! :whistle: goodluck,happy wrenching!

Actually,I think it's a combination of what both Mark and Roland mentioned.They're there to dampen vibration,and I've heard that without them,You can get some pretty serious reverberation sounds...picture the "TING" of a chopsaw with a dull blade,if You will..Lord knows...I heard THAT sound today!:laugh:
I don't think it's a common thing,but there ARE there from factory,so Kawasaki must have had some issues with reverberation.
