Super Jet Squish question

[mitoevo]

Hello
I know the „perfect“ squish is between 0.040-0.045“
My cylinder was grinded and know I need a new base gasket.
i am thinking about to use one to get a squish of 0.05“ because I do a lot of unterwater Freestyle tricks and it can be that there comes some water in into the Engine. I know that it isn’t good but in some challenge you can’t prevent it so I am thinking about to get a higher squish (0.05“) to get a little bit more safety when this happend.
is it okay to run this squish or is there any other risk except to loose some power and decrease the compression ?
I ride a stock 62t case with 61x cylinder Prox pistons ada 35cc Domes in girdle head, v vorce 2 reeds, b pipe, Freeride innovation waterbox and stock air Filter.

I've been told .050-.055" by an engine builder I used to work for. He wasn't a jetski guy, but a 2-stroke wizard for other power sports. He may have told me to use that squish to be safe. Basically, you shouldn't have a problem running with that much.

I just measured a stock 62t cyl/head at .110”. More squish is just less efficient, for a given compression, you’re dropping both compression and squish but you’d have to have a good foot dyno to tell between .05 and .04. I didn’t notice going from 31cc Ada domes to 35cc, besides no longer having to go to the airport for fuel. I have a spreadsheet I could tell you how much you’re dropping tomorrow but I’d be surprised if it was a noticeable difference.
