Hi,
Need to know the squish gap measurement for my L4 engine.
I have just rebuilt the head.
Is it 1mm?
I have 1.22mm now

It’s hard to find specs for these. I might have something buried from when I did a little work with TAGUSA, let me take a look.

If you don’t already have it, here’s the Homologation sheet for the Motori Seven L4 TAG 125cc

Unfortunately (or fortunately depending how you look at it.) it looks like squish wasn’t part of the spec. 1.2 should be safe if everything in the rotating assembly is tight.
