Compression Question

[RacingJake]

Do you think the compression will be higher than 10-1 after using 1425cc 10-1 pistons with a stock GS 1100 4 valve head.

I'm thinking it should be higher sence the pistons are bigger and the oem head was designed for 1075cc.

That may be the case It is best to check it and clearances before assembly

Where do you plan to set the deck height?

[RacingJake]

Good question, Pistons even with the top of the block.

[lecroy]

You can get about any thickness you want. Are you going with an external starter?

[RacingJake]

Nope, still using the push button start stuff.

I'm going to use a bigger battery and install an onboard compressor to keep the air shifter bottle full. Would like to run a full night during test and tune without recharging the battery. A small car type battery should do it.

Try it before you mount it.
