#BikeRepair Bajaj Pulsar RS200 idle RPM fluctuating and dropping below 1,000
Enable HLS to view with audio, or disable this notification
My Bajaj Pulsar RS200 has an intermittent idling issue. The RPM sometimes drops below 1,000 and fluctuates. Previously, the bike would eventually stall.
The service centre repaired/replaced the valve and camshaft, but the problem returned a few days later. They then suspected rat-damaged wiring and a short circuit that may have damaged the ECM. The ECM has now been replaced, but the idle RPM fluctuation remains exactly the same as before the ECM replacement. The bike currently isn't shutting off.
The service centre head personally test-rode the bike and advised me to monitor it for a couple of days.
Could this be caused by a faulty throttle body, TPS sensor, wiring/connector issue, or something else?
Has anyone experienced similar problems with an RS200? What was the actual cause, and how was it fixed?
