Hi. I have a new 200cc that at 2000 km started making a knocking noise. Garage said its a crank bearing. They opened up the motor to see it was a bearing; but due to poor oil pressure on the crank. Only the crank was replaced and now done 300km on it and the bike does not rev or pull through the gears without what i would describe as friction or flat spots. Its not fuel, Chain or mixture. The bike did overheat. Would the cylinder not warp or the rest of the motor been damaged and now causing this lack of power and jerky ride. Dealer says the top of motor got oil so does not matter if it overheated... anybody able to give me some advise.
