Hi Tone,

When I used to run the XP, I likewise found that it liked running
hotter (250 to 270 range). They work in optimum when hot. I
saw them with others and use them myself running at those
temps and stayed there on main events.

By the way, we used to run them with Blue Thunder Race Formula
40% Fuel and with a #8 cold plug. Am not sure if you would like to
try that. Head clearance was 22000.

Those Picco Conical Headers and Pipe work great and they
compliment the XP motor's performance a lot.

Good luck!

Ditto. 30% byrons, Rb#6 plug.
