compression ?

[firemonkey]

i am working on a 96 banshee with a motor bore of 70 over . I have 3 questions

 

1. what should the compression be at, and is 110 on rideside and 115 left side too low?

 

2. what is a stock banshee compression?

Here are some ?'s for you.

Are the jugs ported?

What is the elevation?

Does it have a cool head?

Has the stock head been shaved?

Did the test you used have a check valve in the adapter?

(for what im talking about)

it is not a stock head, the head doesn't use a head gasket it has o- rings and you use some sealer from toyota i have been told that the bike should have 11:1 compression.

no check valve

You should use a snap on compression tester to get a accurate reading. If it's a new motor, you have to break it in first and seat the piston rings to get a reading.

Stock comp. is 115-125 psi.
