Setting Squish

[Banksy]

I have just fitted a Athena cylinder kit, in the book it says to set the squish to 0.8mm.
With the standard base gasket my 1.5mm solder is not even being touched so my question is - should I replace the base gasket with one of the ally ones or machine the head to suite????

(BIG thanks to Darrell from www.50cctuning.com :winner: )

thanks

assemble with ally base gasket until you achieve 0.8 or no base gasket if neccessary either way use a smear of good sealant on both sides to seal as i find air leaks upon leakdown testing if not used

dont worry if its a little different + - 0.05
also use a 9 or 10 plug gapped at 0.4 to 0.45 (thickness of your thumbnail)

Almost never machine the head, if you have the LC O-ring head gasket. If the thinnest base gasket will not give you a closer squish, then machine the base. But you will change the timing a bit.

Thanks, I give the thin Ally base gaskets a go, (its AC) I'll set the spark plug gap using feeler gauges. I get enough dirt under my nails as it is

Set the squish to 0.9mm no base gasket (just blue sealent) and a thiner head gasket. That will have to do as I'm not machining it.
