9rider Posted May 18, 2013 Share Posted May 18, 2013 I accidently threw away the valve cover hose contain the flame arrestor inside. Forgive me for being a newbie to the Z. I replaced it with a normal vacuum hose. So is there a serious negative problem that will affect my engine performance and or emission or safety or gas mileage ? I tried to look up and search for this little flame arrestor to install it back but couldn't find it. Is there another way or mod to correct the problem. Thanks all for your help. Information you guy gave me helping woke up a 10 years sleeping beauty Z. Quote Link to comment Share on other sites More sharing options...
Domzs Posted May 18, 2013 Share Posted May 18, 2013 You can use a regular PCV hose . It's just a crank case breather hose , no flame will come out of the crank case ( hope not ) . You can also pack the hose with coarse steel mesh , make sure it has flow , if that make you feel better . Quote Link to comment Share on other sites More sharing options...
