I forgot you have to mill the valve pockets like 20 thousandths as well

thanks for this info, i can lay my hands on some FZR pistons for around £30.

alos i take it when you say valve pockets you mean the recess in the top of the pistons that are on an anlge.

what does this do to the compression ratio if anything?

[Chris H]

The pockets are machined to stop the valves hitting the piston and is not really relevant to the compression ratio.
The fact you have over bored increases compression.
You should still measure the motor after machining tho, if one pocket is on the high side and its valve slightly longer you could run into problems.
Remember to open the head gasket out to fit the new bore!

[orac]

thats what i thought, was gonna measure things up before final assembly anyway. i have a second set of 400 pistons that i can compare things like pin to crown so i can get an idea of what and where i need to make anychnges

[bandito93]

What about the head and base gaskets, will the factory ones still work with the 59mm pistons? If not where can I find a suitable gasket? My poor Bandit is getting tired and I really would like to do this 442 setup when I rebuild it. Thanks

[Chris H]

Base gasket is stock but head gasket has to openned out by hand to fit the new bore using a dremil etc.
