Suzuki GP100 compression figure?

[cb1rocket]

I'm getting the top end rebuilt on my little 2 stroker.

What should the workshop manual say for the compression figure in psi? Does anyone know cheers

[hmmmnz]

not sure but i was getting 120psi out of a A100 which i was surprised about,

if you do find the ratio,
times it by 14.7 that will give you a perfect world figure

eg say if your bike was 6.7:1 then the psi would be 98.49psi
realistically it will be alot lower, probably around 85psi

thanks mate

compression ratio is 9:1 so i take it that would 132.3 psi - sounds pretty low to me still! Was thinking something more like 150psi at least!

Compression sounds ok but I still think that ring gap is a far better way of gauging the condition of a 2T top end.

well I haven't rebuilt the engine yet - still waiting from the reborers to come back with dimensions and costs to the barrell.

Just saw a clip on youtube for the suzuki gp100 compression test and someone has actually done a video of it showing about 140psi so the 133 psi sounds about right

lets see what mine turns up to be.

Do you need to oil the bore before testing?
