David, I have always been taught that each cylinder should be within 10% of
the others. I would not worry about it. If you JUST finished a rebuild I
would guess it to be closer though. Did you redo the valves? that could be
your problem as well.

Subject: [TR250] compression test
Hi Folks,
I warmed up the motor, removed all spark plugs,
held the throttle wide open, and performed a
compression test on each cylinder in turn. Here's
what I got:
Cyl lbs/in2
1 180
2 180
3 180
4 180
5 180
6 190 <---- The only odd ball.
Seems kind of strange that #6 is so much different
from the other 5. This is a freshly rebuilt engine.
Does this seem okay to you guys?
thanks
David Brady
