OS 91 engine info

[Ihncheol Park]

Hi, Scott,

My 91 SX-H with standard Macs Products' 91FX header and Blue Bird 140 2C
pipe (not available in the states anymore) turns APC 15x8 @ 10250 @21.6"
from glow plug to first baffle.  Not all tuned yet.  This is with Magnum #1
or Coolpower 25%.  I don't remember which fuel I used when measured this.

Hope this helps,

Ihncheol Park

  Good Morning,

  I see that there was some info being kicked around about the os91 2 stroke
engine with props and a head shim, but what is the pipe length to first
baffle from glow plug ( straight line).
  Thanks..
