I have a friend that has a crf150 and needs more power. I said get more airflow. I have a crf250 and cut the box, piped it, and power now on both ends. What a huge differance. Can you put the powernow on a crf150? Any recomendations on a pipe for this bike? Thanks

In my opinion it’s not worth putting a pipe on the 150. Follow the uncorking procedure for the 230 in this thread - http://crfsonly.com/forum/viewtopic.php?t=3414 but do a search for the specific jet sized in the 150 forum. He will be very please with the results…..
