5,000Km is way too early for tappets adjustment? Lol...
Amongst our local bikes, their tappets should be adjusted every 2,000kms at max.
Wrong valve clearance not only results in lack of power, more fuel consumption but can also bend your valves and damage the engine.
Plz get ur bike tuned and tappets adjusted every 2000-2500kms or u will ruin it. GS150 does have hydraulic valves which need less frequent adjustments, but 5,000kms is too much.
2000-2500kms is a safe limit.
