I bought this bike in 2016.My Bike till 40700 km run.About 8 months its very smooth and good in power. But now it producing some unusual sound from chain, vibrating itself when above 40 km speed.while changing my gear from first to second it automatically goes to neutral several times while I take it to the pulsar service center they just adjusted the clutch and told it will not happen again but it has not been resolved and the engine oil has been leaking for nearly 2 months no steps has been taken by the pulsar service center I have mention to them several times but very poor in servicing.
