No, it is not possible to convert a Pulsar 150 with a dual lever gear rod to a single lever setup. The dual lever gear rod system is designed specifically for the Pulsar 150 model and allows for the engagement of multiple gears using separate levers for upshifting and downshifting.
Converting to a single lever system would require significant modifications to the bike's transmission and gear shifting mechanism, which is not a practical or recommended modification. It would involve changing the internal components of the transmission, altering the gear selector mechanism, and potentially affecting the overall functionality and reliability of the bike.
If you are looking for a bike with a single lever gear shifting system, it is advisable to consider models that are designed and equipped with a single lever setup from the manufacturer.
