Hi Pete. Last year when I was doing up my GTS, I bought the OEM 02 sensor from Yamaha. When I got to the exhaust I decided to compare the Yamaha sensor with the Chevy's I changed. The Chevy units were a sure fit. The only difference I noticed was that the Yamaha sensor was of a more compact design. Hence, it would create a little less restriction in the exhaust. On the other hand I checked with some jabber replacement units from the motorcycle distributors & they were also a sure fit & little more compact than the Chevy units. As far as changing your unit ? Well you got your GTS for a while now, so it probably won't hurt. Keep us posted on your findings. Be good.
