AIS Block Off Plate

How thick should it be?
Also dimensions would be useful.
Thanks

All kinds of info in this thread:

Holler back and let us know how it goes. I'm studying on this, too. Thanks

I made my own.

Thickness is not important. As long as your srews don't bottom out before a seal is made between your plate and the cylinder head you're okay.

I removed the AIS piece, placed it on a piece of 0.070 thick aluminum sheet, traced a line with a pencil, and hacked away with a hacksaw, then filed the sharp edges.

Cost me nothing but time. It was kinda fun though so......

What did you use for a gasket? Is heat an issue?

I belive you just reuse the stock gasket.

yea...just re-use the stock gasket.
i made my block off plate from .250" billet stock...milled down to .160" thickness,if i'm remembering correctly.

I made my own with 1/4" aluminum and my Dremel.

I went with 2mm stainless steel, orignal gasket and a jigsaw.
Hard enough, stiff enough and should hardly corrode at all.
Used the rest of the steel to tidy up the rear end/plate holder.

Steel! for a plate holder it's not to heavy is it?
I just used plastic.

Thanks for the info guys it's it seams like I can make it any thickness i've got. Can't wait for that exhaust to get here.

I used steel for a few reasons. I had the bit lying around, it's not heavy by any stretch, the legal plate is enormous, I can attach a small mudguard if I want and I am still considering drilling holes out of it to make it lighter.

Thanks for all your suggestions .
I ended up making mine out of 6mm aluminum and re-using the stock gasket.
The whole AIS unit weighed in at 475g .
