Eton Viper 90 Compression (New Top End)
What should the compression be on a fresh top end on a Viper 90 2 stroke. 2005 Model.
I just did the top end with a Eton top end kit, (new cylinder and piston)
I am running some 40 to 1 pre mix for break in.
Compression is only 90 PSI, I did check it with the throttle wide open.
