1980 kz 550 emission valves at top of cyl head

Hi im looking for info on how to elimenate the emission valve on the top of the cam covers on my bike,they are noisey and un needed,any advice would be great thanks gary

There are cover plates that you can purchase to block off the head ports here: Z1 Enterprises
call Jeff @ Z1 and he will let you know what you can/cant use for your model.

Or you can just jump a length of hose form one cam cover cap to the other.

This company might be able to make you some custom block off plates:https://www.tpoparts.com/cat093/index.php?route=product/category&path=74

Recently, I used their kit to block off the emission reeds on my 1982 GPz1100 B2 model. The kit came with two (2) plates, instructions, and vinyl caps for hoses.
