250r clearance question?

[barbwire44]

Just wanting to know what you guys are setting youre piston to head clearance (squish). Im running an 88 motor with an 88 jug and an 86 piston with a spacer at .100 over. I was thinking of .040?:D

my head is cut on mine. Im not sure how much, but my compression is 204 PSI with a stock head gasket.

I have heard that you can change the compression with a larger or smaller spacer plate.

When I do my top end this time around I am using an 86 piston and my spacer plate. I will check the compression and see if it gains or loses compression(I am hoping I will lose some compression so I can run 93 in it)

we shall see.

i have an 86 motor, cranck, and piston, my squish is .040. my buddy has an 88 motor, crank and piston and his is the same

well, my squish is definatly less than stock.

id say .022???

I dont feel like getting some oil and measuring my squish with a bottle that measures how many cc's the head area will take. So I am just guessing.

[barbwire44]

are you guys measuring with clay or solder or?

i measured with solder,
i thought anything les then .030 was dangerious because when the parts in there get hot the sweel and may possibly hit???
