Suzuki 115 o2 sensor

[Karnic]

Hi all. Would like your help about an issue bothering me again. Suzuki DF115 ATL 230 hrs changed o2 sensor 3 times already. Last time i got the new superseded one but to no avail. Could some one enlighten me whats happenning that sensor need to be changed so often. Voltage ok. Alarm sounding occasionally not always. Any1 have these issues with Suzukis?

Got the same engine with 400 hours on it and never had a problem with an o2 sensor.

Fault with the fault sensing system?

Could be a fuel or ignition related issue, you’d think ? If it’s triggering the o2 sensor. I’d have a check on the plugs for colour and see if there is any indication from them
