Musarri Exhaust
« on: August 12, 2017, 12:46:39 PM »
Hi all,
I am after some advice.
I have just fitted the Musarri full exhaust to my 650 and it does sound much better but it definitely hampers performance. The engine takes more time to spin up and drop down. I spoke to my local dealer about this and they said it could take up to 3 months for the adaptive fuelling to get used to the new exhaust. Are they talking pants or will I have to get the ecu remapped or fit a power commander. I have added a short clip of the exhaust.
Thanks in advance,

Did the new exhaust have a fitting for the O2 sensor?

Yes, there is a connection for the lambda sensor.

Yes, the ECU shouldn't take long at all to adapt to different conditions. That is like saying if you moved to a new house which was at a high altitude the bike would take 3 months to adapt to it. The more likely explanation is that your new exhaust is flowing so well the ECU can't adapt to it properly and the fueling is now running lean.

Thanks for the reply Dr Bones.
Does it now mean I need to get the ecu re-mapped?

I'd certainly get the fueling checked to make sure it isn't too lean. The stock ECU can only adapt so far to changes to the bike and it'll already be running pretty lean to start with to meet the EU emissions regulations.
