Kevin, That is chilling news and an indication that Harley has chosen to stay in line with their consent decree and keep their dealers in line in terms of mods that would affect the EPA mandates. I for one do not want to have my Harley-sourced ESP contract for my 2017 TGU voided for a powertrain that has yet to prove its long-term reliability. Additionally, it seems that some of the mods people have been attempting on the M8 engines are proving to be going in the opposite direction that was intended and with few anecdotal reports are experiencing some decreased performance and smooth running.

Yep.....Some mistakenly think a louder exhaust, And a louder air cleaner equal more horsepower....Usually its just the opposite....:xzqxz:
