Cleaning under plenum - ZR-1 Net Registry Forums

DaveK · 09-21-2023

Hi everyone,

I've removed the plenum to switch out the starter motor and there's a lot of thick black grime underneath. Any suggestions for the best way of cleaning there?

Also, this plastic clip crumbled when I moved one of the lines. Are they available anywhere?

Thanks
Dave

I use mineral spirit, a toothbrush and a lot of rags. Once cleaned, fresh injector housing gasket and positive seal at PVC hoses should keep it reasonably clean.

Thanks, I'll try that

Put duct tape over intake ports to prevent anything falling in there. Don?t have an oops.

Thanks, Steve. I did that a couple of minutes after taking the photo

I'd suggest if you're not in a hurry to get it back together pull everything out off,clean and put it back together.
