They’re Parma kit pistons, but this kit is like 8 years old at least. I may have been able to run it with just a fatty gasket and a head with squish cut, but nah. I prefer the metal spacer and this way I was able to use this a55 head I turned for a puch reed kit years ago, but the puch studs weren’t long enough. Seemingly the rippiest tomos kit out of the box. Whitey is going full stupid on an alukit we shall see if it hold together.
