Nels,
From Burton's site...
"Barrel and piston set, Big Bore 2CV6 652cc, 9.0:1"
Also, this advice. ( Proofreading foc, solely to correct spelling errors.
)
"This cylinder kit needs to be run in.
We advise you to not drive faster than 80 km/h or 4,000 rpm for the first 2,000 kms.
After this period, steadily increase your speed.
Only after a careful running-in period will your engine reach its full power potential."
p.s. With a standard camshaft and cylinder heads, you'd be looking at 175 psi, with engine warm and 'wide open throttle'...

I've now got a compression tester - any ideas people on what sort of figures I should be seeing on my 652cc which I think is 8.5:1?
