I thought about getting the CRF but i've heard from numerous people that the orion motors are finiky to tune and you have to have a perfect tune on them to get them to run good. I'm not the best tuner in the world so i've talked myself out of getting one. I just wanted to confirm that they are fairly hard to tune for the average tuner. Also what's the CRF getting for gas mileage?

Thanks, Garrett
