I think there is two versions... the one in europe is NS based and has the small heatsink.... the Us version is a RR with large (tall) heatsink ???

Ive got my x12 modified by Uriah Murnan and this thing is ballistic. Im spinning 35 shore tires a good 30 down the straight and i have barely gotten the engine over 200 degrees. These engines are screamers. Robbie at mugen said they used a short stroke conrod with a longer stroke p/s, but the moved the pin on the crankshaft out a little more to get the better powerband and let me tell you it worked. Thanks Uriah I love this motor.

I am confused about that last post.
Daves Engine will be ok even if it does not last.
You know why. They Make more. He can get another one.

Oh, I was looking for a temp. I understand the less Fuel/air ratio.
Just curious what you think is to lean by temps. But you really cant go by that totally.

I use the Paris glow plug check. Using new plug, after about 4-5 minutes running, check the plug. If it's slightly gray (not shiny) and dry with no distorted coil, you are perfect. If the wire starts to distort it's too lean. If the wire is still shiny, but the plug is dry your at about 95%.
