Suggest good and well experienced bike repair centres/mechanics in indore

Hi everyone, I purchased a Royal Enfield Meteor 350 around 6-7 months ago, and I’ve been experiencing an issue with tappet noise ever since the first service. During the second service, I specifically informed the service center about the noise. They assured me they would address it, but unfortunately, they didn’t resolve the issue, and the noise persists. I’m now considering having the bike checked by a mechanic or repair center outside the official service network. Could you recommend any reliable repair centers or mechanics who can fix this issue without overcharging? Also, do you think I should go ahead with this or let it be? Could this noise indicate potential damage to the engine? Your advice would be greatly appreciated. Thanks in advance!
