This 2016 Yamaha XSR900 was booked in with us for ecu re-mapping. The bike was fitted with a full Akrapovic exhaust system with baffle in situe, but like all the modern bikes, it suffered from the on/off throttle problems.

The emission controls get switched off and the lamba sensor is removed and replaced by a lambda bung, then we can fuel the bike properly to suit the changes that have been made.

Results are a rider friendly bike that you are in control off in all situations and at all speeds!
