O2 Sensor Retrofit - Calling European Versys 650 Owners
I just came home from riding in the mountains, I was riding my GSXR 750 and only had to refuel once. That is a bike with a larger engine that produces more than twice as much power as the Versys, yet it gets similar MPGs at moderate speeds and just plain puts the Versys to shame if the ride gets spirited. Only thing I can think of that could account for that difference is the fact that my EPA spec Versys is open loop while my EPA spec GSXR is closed loop.
2010-2014 Versys have a fuse for an O2 sensor that is not there, and there is a free connector by the countershaft cover; Looks like Kawasaki cheapened out and figured it'd be cheaper to use the same wiring harness for all of them. So...
- ECE ECU
- O2 sensor.
- Weld O2 bung in muffler or swap an ECE muffler.
That should be enough to convert my EPA Versys to ECE spec. I've already done the cross reference:
- EPA, CARB use a different ECU than ECE.
- EPA, CARB use a different muffler than ECE.
- EPA, CARB and ECE use the same wiring harness.
BUT there is something that doesn't make sense. IIRC the immobilizer is mandatory for ECE spec bikes, yet my cross reference shows that all of them use the same tacho/speedo, which means there is no immobilizer warning light, same ignition cylinder without RFID reader and the same non-RFID key... That makes me doubt the accuracy of my cross reference.
So I need European MK2 650 owners to confirm if they have or not an immobilizer.
By the way, I also found that:
- EPA/CARB MK1 Versys does not share the wiring harness with ECE bikes.
- EPA and CARB bikes have the same ECU; the tune is exactly the same.
- ABS and non-ABS bikes have the same ECU.
- Wiring harness and speedo/tacho are different for ABS and non-ABS.
- Stator and RR are the same for all. <--- Non ABS Versys has more available power to run gadgets / lights / heated gear.
