First two indicate front and rear inactive 02 sensor, last three indicate issue with your throttle grip sensor (TBW). The throttle issue could likely be the pins at the sensor plug by the throttle body.

1) P0134 Front O2 sensor High or Open
2) P0154 Rear O2 sensor High or Open
3) P1510 Limited Performance from Throttle Control
4) P2127 Twistgrip Position Sensor Low or Open
5) P2138 Twistgrip Position Sensor Correlation Error

For items 1 &2 check to make sure that the O2's are plugged in properly and then look to see if you have a bad fuse for the O2 heaters
Items 3 to 5 are all from one problem which is item #4 fix it and the others will be fixed as well. As mentioned unplug the connection at the throttle body and clean it then plug back in. Clear codes and see if they come back. If this fixes it, your looking at a pin problem but may get you by for awhile.
