Hi All
I'm at the stage of my rebuild where I'm ready to fit the barrels & heads.Is it necessary to measure the squish and if so,what should it be for a standard 906 motor.I have searched the forum & manuals but there is little information on the subject.

1,0 mm is usually recommended as optimal & safe w standard conrods.

Thanks Gert.
So far I've measured the vertical cylinder using some soft solder and it has 1.36mm clearance.
This is the first time I've dealt with this issue.Is 0.36 mm worth worrying about?

Got this link from jcslocum when i rebuildt my top end.

I measured the front cylinder last night and it was 1.00mm so all good there.I'm going to double check
the rear cylinder again tonight if it still measures at 1.36 then I'll look at getting another base gasket for it.

Thanks h1a for the link,lots of good info there.

It wont run bad w 1,36mm squish, most Ducs have that from factory.
Just if you want to blueprint measures, around 1,0mm is close to optimum.
A good idea is to have same figures on both cyls.

very clean looking pic, Nice work

I checked the rear cylinder again last night and I got the same measurement so I bought some
shim and cut myself a new gasket.It measures the same as the front cylinder now.Happy days

What material did you use??

I use the wax to measure squish and it works really well. Remember to put the gasket sealer on very thin or it will change your dimensions and could gunk up your oil passages.

I used stainless steel shim
