Piston squish

[SJet]

Hey Guys

I did a little work to my stock 701 cyl. I had to take .020" off the bottom. I put her all together and checked the piston squish with some solder. I am reading .030" piston squish.

Should this engine be okay? I imagine it will make more power, but will it live?

Thanks

That's pretty tight. What's your base gasket thickness, and what head are you running?

Its tighter than i would want to go thats for sure

Well, I am running a .020" base gasket, I think that is stock? I have the ada head and I have the 35cc domes in there now.

What are the issues of running .030" piston squish? Should I try to get .040"?

Thanks

I believe you want 0.045" min for pumpgas.

I guess I will get a .040" base gasket. That will get me .050" squish, which should be fairly safe.

Need way more bbrraaap!!!!

Yes I would do this. .030 is too tight. I run .050

It would be better to cut domes, as to keep the cylinder lower for freestyle.
