stock ignition is 16 degrees, you can advance 2 degrees to 18

on the compression test, you dunt want less than 210 across the board

Isn't 210 a bit on the high side for a motor with stock compression?

well i guess it does depend but ive had GSRs rebuilt with 210-220 across the board, anything less seems to be from valve seals or piston rings

 

You want more than 185 on your compression bro!
