Glen Davis Posted April 4, 2021 Report Share Posted April 4, 2021 I'm having Aerocomfort rebuild the glairshield from my 1984 M20J. He contacted me on Friday stating my glairshield has a "ventilation screen" on the top about 3 x 5 inches which is "not standard". He wants to know if I want to keep the screen or if he can cover it with the fabric he is using to cover the rest of the glairshield. Does anyone else have this screen and is it necessary? See photo attached. Thanks. Glen Glairshield.HEIC Quote Link to comment Share on other sites More sharing options...
GeeBee Posted April 4, 2021 Report Share Posted April 4, 2021 Cooler is always better, except on cylinder heads below 250! Quote Link to comment Share on other sites More sharing options...
ArtVandelay Posted April 4, 2021 Report Share Posted April 4, 2021 You shouldn’t need the vent. Quote Link to comment Share on other sites More sharing options...
BaldEagle Posted April 4, 2021 Report Share Posted April 4, 2021 I have the vents on my J and just covered them up when I refurbished mine. Quote Link to comment Share on other sites More sharing options...
Glen Davis Posted April 4, 2021 Author Report Share Posted April 4, 2021 I'm thinking ventilation screens were added when radios were more prone to overheating issues. I believe newer equipment is less susceptible to overheating. Unless I find out otherwise, the screen will be history! Quote Link to comment Share on other sites More sharing options...
carusoam Posted April 4, 2021 Report Share Posted April 4, 2021 Looks like it is an add on... Next steps... Determine why they added that on? Then decide if that reason still exists... Got a pic of what is under there? From the top and from the front... Best regards, -a- 1 Quote Link to comment Share on other sites More sharing options...
gsxrpilot Posted April 4, 2021 Report Share Posted April 4, 2021 I'd cover it. Quote Link to comment Share on other sites More sharing options...
