Considering taking the advice given here and attempting to change the eprom chip in my bike anyone have suggestions or pointers on exactly how to change and where it’s located and why?

Hi Nick,

Not all the ST's had ECUs where you could replace the EPROM. What year is your bike.

It's helpful to add your bike's details to your signature line. You can do it though your user control panel.

The pop on deceleration can be a sign of a lean mixture. How long since the last service (valve clearance adjust, throttle body sync, fuel trim adjust)? Does the bike have OEM exhaust and unmodified air box? If the cans have been switched out for aftermarket (Termi, DP, etc.) and the air box drilled, this will make it run lean too and an EPROM would be the solution.
