This might be slighty off topic, but im in the middle of breaking in my JL .12 RD (not the evo) in my CRT.5. Im on my... (8th? tank).. I think its been through 8 tanks.. anyways, the motor is starting show its wild side. I just started to lean it out.. and it has SERIOUS power, and its still running pig rich. Another thing is, the pinch at the top of cylinder is still there... is that normal? Ive had numerous piccos in the past (none that were turbo).. and the pinch would go away after 6 tanks or so. Im taking the engine temp up to 160-170 degrees F. When i shut it off, its a little bit loser, but as soon as it cools, the pinch is super tight.

Should i put more heat in the engine? Ive already been doing 2-3 second 100% throttle runs. Im kind of afraid to lean it out anymore, simply because this thing makes so much damn power, its lifting the fronts off the ground (not good with 4wd). Any ideas?
