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?

well, i know that the temp should be 200-220 degrees. im guessing it shouldnt be much diefferent than an on road engine. and it doesnt sound like u r running rich. and besides, it alkways better to have it a little rich than too lean!

i dont own an RB, but i hear that they like to be rich on the bottom and lean up top (someone chime in and correct me if im wrong).
