Crossflow vs. Looper

[Skools Out]

is that on an outboard? that compression is too high for stock heads, crank, rods, and starter. i have a racing jet ski with all race mods stock was 90 PSI now 230 PSI. but once you get that high on a 2 stroke you have to weld the crank so the plates don't turn. You have to use better rods as well.
