Power Valve Spacer

Thanks for the photos but would be handy to know the thickness for a 300.
Will try making my own once I know how wide they are meant to be.

If you can draw the profile in a CAD program, anyone with a Waterjet can cut the aluminum easily in your preferred thickness.

Ok, so I take it the thickness is not important then?
How wide can you go before it effects the bike adversly?

I will measure my LTR to night and tell you what thickness it is.

Same thing I was thinking. What effect does the thickness
have on chamber volume and power output? My thought was
to make spacers and stack them up with gaskets between
them. You could start with maybe 1/4-1/2 inch and see when
and where the power or torque changes.
Someone, maybe LTR or GG, has already experimented with this and
ended up with the thickness they sell as being the optimum.
The change may be so slight as not to be even worth the effort.
I'll file this away as a future project to get to after all the other
foolish projects I have in mind get done.

Dingo measured his spacer and found it to be 20mm.
Found info on another thread...

I have one like yours. It's made by Perfex (it's me!) for $69.95, part number 1198-GE25. It's 3/4" thick, and it makes a very good diference. Much more torque at low RPM. In the very technical trail, you can ride so slow you can feel each explosions in the cylinder. You don't need to change the jetting.
