Decompression Block-Off 99 400F

I have a decompression cam for me YZ 400F. Does anyone know of an after market block off kit to replace the decomp parts in the head?

Somebody sells a plug for it on E-bay.

18mm expansion plug (freeze plug) from an auto parts store. $1

Great idea, thanks.

Went to my local Autozone first- guys there didn't know what a freeze plug was and couldn't find in the computer since it is set up to search by year/auto make/model.

Went to NAPA alittle further away and they had them for 0.69 cents-steel only, but I'm not sure it makes a difference (brass or steel). I bought 4 since you may mess them up installing.

This is how I did it (found in another thread from Grayracer):

You might be able to fit a C clamp in there and press it in that way? Otherwise remove right radiator and get a straight shot with hammer and socket.

Use red locktight on the plug. The plugs come in flat, shallow and deep. I think I got the deep cup shape which is not that deep-about 4-5mm deep if I remember right. Drive it in until the lip is flush with the surface of the cylinder head or it bottoms out.

Way to go, buddy...welcome to the 21st century!

You can find a plug on e-Bay if you don't want to go the freeze plug route.
