Will this valve spring compressor work for a yz400f?

I measured the outer diameter on one of the valves and got 19.76mm, I just don't know if the 19mm attachment would fit. :thumbsup:

The question is what the diameter of the retainers and the lifter bores are.

Oh, that's the part I didn't understand.

I'll go measure them.

Thanks Gray.

The lifter bore is around 22.75mm and the od of the retainer is around 19.25mm.

So I don't know if the 23mm-21.5mm adapter would work?

Probably the 19mm.

Ok. Thanks Gray.

Now I just need to get my 400 rebuilt and back together. :thumbsup:
