I asked about the ECU recall & was told there is no recall for ECU's on any XT660X, I know better.

Well I'm off now, I did not even get to the end of their driveway & my bike stalled, restarted & got to the end of the street the bike stalled again. Gee I said to myself this new part works well. Anyway I went home, I have reset the TPS to my settings & reset the idle from 1270RPM to 1450RPM & now it's all good.

What I have found with the new TPS it's made by Mikuni 466x11 A1, it has a different scale for reading the throttle angle. I'm not sure about where they are going with this new TPS. If the TPS is set to 18 when the throttle is closed the max throttle reading is only 95%. If you set the TPS to read 100% the closed throttle reading is 23 on the dash that's out of the idle spec, if set to any of these readings it will be out of range either end. I will write to Yamaha technical to see what they have say.

Also if you have a Power Commander & have had the recalled TPS fitted you need to reset throttle position for the map, other wise the Power Commander will be giving the incorrect fuelling at all throttle ranges. This is due to the different throttle angle scale from the new TPS.

Resetting the throttle. Set the bike up with the USB & power supply, make sure the ignition is on as well, get the map, click on Power Commander tools, click on set throttle position. Then a new screen will appear for the throttle setting, click on reset, twist the throttle all the way to full throttle slowly then back to the rest position, then click ok to save.

A little feed back, my bike is still cutting out after fitting the new recalled TPS. I removed every mod on my bike & put it back to std & it still cuts out.

I wrote to Yamaha Australia & had a responce & now have to take my bike back to the shop for a second TPS, as I never had a problem with cutting out until they fitted the new TPS.

Before someone asks, I did recheck all the settings & fitment. The installation is correct & my testing of the TPS I could not fault it.

I will update you with the out come.
