I think it was a bad move. Unless your cylinders are finished your stock cylinders are the way to go. Athena has bad plating and port timings I’ve read makes the power band narrow. You would have been better getting Driveline cylinders which have taken that design and improved it and drastically improved the plating.
On and popping [emoji41]. Started right up. Pretty impressed so far. Install wasn’t bad and of course I added a few extra things, such as wire and lipo heat protection ect ect. Sounds a little more snappy. Just have to wait until the snow is gone before the test ride. Sent from my iPhone using Tapatalk
