FMF Powercore 4 HEX
« on: September 29, 2021, 05:11:10 PM »
 I have 2015 Sherco 300 SEF-R. I replaced the stock "Big One" muffler for FMF Powercore 4 HEX. It does lean condition and puffin in the muffler when turn off the gas. What should I do? Reprogram or change ECU? If need to change ECU, which part number?
