he bought it from Commonwealth Motorcycles in USA.
His bike gets some issue after installs that Termignoni exhaust:
- odometer goes wrong . it increase 40% with other
- there is backfire when i throttle down
would you give us some advice.
That kit comes with an ECU - ensure it's displaying Miles not Kilometers. A sudden 40% jump in the odometer reading is probably due to it changing it Kms
For the popping - there's probably a leak in the exhaust. Re-fit the slip-on cans and ensure they are sealed well. Some exhaust sealant can be used to help make sure there are no leaks.
Popping on deceleration is a common symptom of a leak, and with the fact that you/he just changed out the slip-ons I'd lay good odds to it.
