Today changed the engine oil (Liqui Moly) at 400 kms and clean the oil filter with kerosene oil. AlhamdoLillah no more issues yet except that traditional "Khatak" sound which comes once or twice in a day and disappears automatically, normaly, when shift the gear from neutral to 1st (I think it comes when engine is not properly warmed, though, i always warm up the engine for three to four minutes before drive). After the oil change the bike is more smooth and lesser sound.Overall i like the ride except some quality issues that are common like poor paint quality and very pathetic chrome there is already stains at chromes area which shouldn't be at this level of bike/price.
