I recently just broke in my new MBX5 prospec with RBc5 buggy coupled with RDlogics pipe. it went through 12 tanks running at around 160-200 degrees. i started to lean it out to 215-230 degrees lately and the c5 starting to come alive. i have enough power to clear jumps, however people tells me i am running it rich and i can hear the engine 4-stroking. i can tune on road engine no question about that: but is the off road engine any different? and what would that do the temp. what is the ideal temp for this engine or any off road for that matter?
