You can not compare PSI to 10:1, 11:1 etc. Its not the same. There is no rule saying this many PSI equals this much compression. My LT1 in my Z28 is a 11.7:1 motor but I bet my cranking PSI is about 120. How is this? My cam has a lot of overlap.
A 4-stroke is a lot different than a 2-stroke(obviously). A banshee, 250r, or whatever might have 130PSI when you kick it with a gauge on it, but think what it might have at WOT. Everyone here says 150 is the limit with 93 anything more than that is playing with fire, why not believe them. Remember your Banshee doesnt have a computer, knock sensor or any other little things that can tell when somethings not right like my Z28 or your Honda does, it will just run untill it blows.
Can you afford to be stupid and ignorant?
