Hello, my name is anil kumar... I have purchased royal enfield classic 350 signal strom rider sand edition bike on october 2019.. The thing is i have noticed a problem at engine from the beginning like the bike can be kick start by holding clutch and able to hear some un wanted sound from engine this happens only after parking bike for long time.. I took to service center many times and explained the problem but could not show the problem practically because it happens only if the bike is parked whole night... I feel its a manufacturer defect.
